Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573688, here are decompositions:

61 + 31573627 = 31573688
67 + 31573621 = 31573688
127 + 31573561 = 31573688
331 + 31573357 = 31573688
409 + 31573279 = 31573688
499 + 31573189 = 31573688
577 + 31573111 = 31573688
631 + 31573057 = 31573688

Showing the first eight; more decompositions exist.
