Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747278, here are decompositions:

  • 5 + 8747273 = 8747278
  • 17 + 8747261 = 8747278
  • 107 + 8747171 = 8747278
  • 167 + 8747111 = 8747278
  • 311 + 8746967 = 8747278
  • 359 + 8746919 = 8747278
  • 431 + 8746847 = 8747278
  • 467 + 8746811 = 8747278

Showing the first eight; more decompositions exist.
