Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577446, here are decompositions:

29 + 31577417 = 31577446
53 + 31577393 = 31577446
59 + 31577387 = 31577446
83 + 31577363 = 31577446
317 + 31577129 = 31577446
389 + 31577057 = 31577446
479 + 31576967 = 31577446
557 + 31576889 = 31577446

Showing the first eight; more decompositions exist.
