Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544356, here are decompositions:

59 + 31544297 = 31544356
149 + 31544207 = 31544356
167 + 31544189 = 31544356
257 + 31544099 = 31544356
317 + 31544039 = 31544356
359 + 31543997 = 31544356
443 + 31543913 = 31544356
449 + 31543907 = 31544356

Showing the first eight; more decompositions exist.
