Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147429394, here are decompositions:

  • 31 + 2147429363 = 2147429394
  • 41 + 2147429353 = 2147429394
  • 43 + 2147429351 = 2147429394
  • 83 + 2147429311 = 2147429394
  • 113 + 2147429281 = 2147429394
  • 157 + 2147429237 = 2147429394
  • 181 + 2147429213 = 2147429394
  • 197 + 2147429197 = 2147429394

Showing the first eight; more decompositions exist.
