Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544474, here are decompositions:

  • 103 + 31544371 = 31544474
  • 127 + 31544347 = 31544474
  • 151 + 31544323 = 31544474
  • 163 + 31544311 = 31544474
  • 193 + 31544281 = 31544474
  • 307 + 31544167 = 31544474
  • 397 + 31544077 = 31544474
  • 421 + 31544053 = 31544474

Showing the first eight; more decompositions exist.
