Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8723402, here are decompositions:

  • 3 + 8723399 = 8723402
  • 43 + 8723359 = 8723402
  • 199 + 8723203 = 8723402
  • 211 + 8723191 = 8723402
  • 313 + 8723089 = 8723402
  • 349 + 8723053 = 8723402
  • 409 + 8722993 = 8723402
  • 421 + 8722981 = 8723402

Showing the first eight; more decompositions exist.
