Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541704, here are decompositions:

11 + 31541693 = 31541704
53 + 31541651 = 31541704
71 + 31541633 = 31541704
107 + 31541597 = 31541704
113 + 31541591 = 31541704
197 + 31541507 = 31541704
461 + 31541243 = 31541704
563 + 31541141 = 31541704

Showing the first eight; more decompositions exist.
