Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747400, here are decompositions:

  • 19 + 8747381 = 8747400
  • 71 + 8747329 = 8747400
  • 73 + 8747327 = 8747400
  • 127 + 8747273 = 8747400
  • 139 + 8747261 = 8747400
  • 149 + 8747251 = 8747400
  • 157 + 8747243 = 8747400
  • 229 + 8747171 = 8747400

Showing the first eight; more decompositions exist.
