Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577062, here are decompositions:

5 + 31577057 = 31577062
53 + 31577009 = 31577062
71 + 31576991 = 31577062
113 + 31576949 = 31577062
131 + 31576931 = 31577062
173 + 31576889 = 31577062
311 + 31576751 = 31577062
353 + 31576709 = 31577062

Showing the first eight; more decompositions exist.
