Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541752, here are decompositions:

59 + 31541693 = 31541752
101 + 31541651 = 31541752
269 + 31541483 = 31541752
353 + 31541399 = 31541752
509 + 31541243 = 31541752
701 + 31541051 = 31541752
761 + 31540991 = 31541752
773 + 31540979 = 31541752

Showing the first eight; more decompositions exist.
