Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544126, here are decompositions:

37 + 31544089 = 31544126
73 + 31544053 = 31544126
139 + 31543987 = 31544126
199 + 31543927 = 31544126
223 + 31543903 = 31544126
283 + 31543843 = 31544126
349 + 31543777 = 31544126
457 + 31543669 = 31544126

Showing the first eight; more decompositions exist.
