Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577296, here are decompositions:

5 + 31577291 = 31577296
137 + 31577159 = 31577296
167 + 31577129 = 31577296
239 + 31577057 = 31577296
347 + 31576949 = 31577296
557 + 31576739 = 31577296
587 + 31576709 = 31577296
593 + 31576703 = 31577296

Showing the first eight; more decompositions exist.
