Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544060, here are decompositions:

3 + 31544057 = 31544060
7 + 31544053 = 31544060
19 + 31544041 = 31544060
73 + 31543987 = 31544060
157 + 31543903 = 31544060
277 + 31543783 = 31544060
283 + 31543777 = 31544060
337 + 31543723 = 31544060

Showing the first eight; more decompositions exist.
