Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544102, here are decompositions:

3 + 31544099 = 31544102
13 + 31544089 = 31544102
61 + 31544041 = 31544102
199 + 31543903 = 31544102
229 + 31543873 = 31544102
379 + 31543723 = 31544102
433 + 31543669 = 31544102
523 + 31543579 = 31544102

Showing the first eight; more decompositions exist.
