Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577632, here are decompositions:

41 + 31577591 = 31577632
101 + 31577531 = 31577632
239 + 31577393 = 31577632
263 + 31577369 = 31577632
269 + 31577363 = 31577632
503 + 31577129 = 31577632
641 + 31576991 = 31577632
683 + 31576949 = 31577632

Showing the first eight; more decompositions exist.
