Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577362, here are decompositions:

71 + 31577291 = 31577362
101 + 31577261 = 31577362
233 + 31577129 = 31577362
281 + 31577081 = 31577362
353 + 31577009 = 31577362
431 + 31576931 = 31577362
461 + 31576901 = 31577362
653 + 31576709 = 31577362

Showing the first eight; more decompositions exist.
