Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987480, here are decompositions:

  • 7 + 987473 = 987480
  • 17 + 987463 = 987480
  • 23 + 987457 = 987480
  • 47 + 987433 = 987480
  • 89 + 987391 = 987480
  • 97 + 987383 = 987480
  • 127 + 987353 = 987480
  • 167 + 987313 = 987480

Showing the first eight; more decompositions exist.
