Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460474, here are decompositions:

  • 43 + 31460431 = 31460474
  • 61 + 31460413 = 31460474
  • 127 + 31460347 = 31460474
  • 181 + 31460293 = 31460474
  • 193 + 31460281 = 31460474
  • 211 + 31460263 = 31460474
  • 277 + 31460197 = 31460474
  • 307 + 31460167 = 31460474

Showing the first eight; more decompositions exist.
