Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147587508, here are decompositions:

  • 61 + 2147587447 = 2147587508
  • 139 + 2147587369 = 2147587508
  • 151 + 2147587357 = 2147587508
  • 211 + 2147587297 = 2147587508
  • 349 + 2147587159 = 2147587508
  • 397 + 2147587111 = 2147587508
  • 421 + 2147587087 = 2147587508
  • 457 + 2147587051 = 2147587508

Showing the first eight; more decompositions exist.
