Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544012, here are decompositions:

109 + 31543903 = 31544012
139 + 31543873 = 31544012
229 + 31543783 = 31544012
433 + 31543579 = 31544012
523 + 31543489 = 31544012
739 + 31543273 = 31544012
769 + 31543243 = 31544012
1021 + 31542991 = 31544012

Showing the first eight; more decompositions exist.
