Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544336, here are decompositions:

13 + 31544323 = 31544336
157 + 31544179 = 31544336
283 + 31544053 = 31544336
349 + 31543987 = 31544336
409 + 31543927 = 31544336
433 + 31543903 = 31544336
463 + 31543873 = 31544336
613 + 31543723 = 31544336

Showing the first eight; more decompositions exist.
