Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544332, here are decompositions:

179 + 31544153 = 31544332
233 + 31544099 = 31544332
293 + 31544039 = 31544332
311 + 31544021 = 31544332
353 + 31543979 = 31544332
419 + 31543913 = 31544332
461 + 31543871 = 31544332
503 + 31543829 = 31544332

Showing the first eight; more decompositions exist.
