Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544512, here are decompositions:

3 + 31544509 = 31544512
149 + 31544363 = 31544512
359 + 31544153 = 31544512
479 + 31544033 = 31544512
491 + 31544021 = 31544512
521 + 31543991 = 31544512
599 + 31543913 = 31544512
641 + 31543871 = 31544512

Showing the first eight; more decompositions exist.
