Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577368, here are decompositions:

5 + 31577363 = 31577368
107 + 31577261 = 31577368
239 + 31577129 = 31577368
311 + 31577057 = 31577368
359 + 31577009 = 31577368
401 + 31576967 = 31577368
419 + 31576949 = 31577368
467 + 31576901 = 31577368

Showing the first eight; more decompositions exist.
