Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147587090, here are decompositions:

  • 3 + 2147587087 = 2147587090
  • 29 + 2147587061 = 2147587090
  • 137 + 2147586953 = 2147587090
  • 149 + 2147586941 = 2147587090
  • 179 + 2147586911 = 2147587090
  • 347 + 2147586743 = 2147587090
  • 359 + 2147586731 = 2147587090
  • 479 + 2147586611 = 2147587090

Showing the first eight; more decompositions exist.
