Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544032, here are decompositions:

11 + 31544021 = 31544032
41 + 31543991 = 31544032
53 + 31543979 = 31544032
71 + 31543961 = 31544032
173 + 31543859 = 31544032
263 + 31543769 = 31544032
269 + 31543763 = 31544032
281 + 31543751 = 31544032

Showing the first eight; more decompositions exist.
