Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747392, here are decompositions:

  • 11 + 8747381 = 8747392
  • 131 + 8747261 = 8747392
  • 149 + 8747243 = 8747392
  • 179 + 8747213 = 8747392
  • 233 + 8747159 = 8747392
  • 281 + 8747111 = 8747392
  • 443 + 8746949 = 8747392
  • 593 + 8746799 = 8747392

Showing the first eight; more decompositions exist.
