Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541692, here are decompositions:

41 + 31541651 = 31541692
59 + 31541633 = 31541692
101 + 31541591 = 31541692
263 + 31541429 = 31541692
293 + 31541399 = 31541692
449 + 31541243 = 31541692
563 + 31541129 = 31541692
641 + 31541051 = 31541692

Showing the first eight; more decompositions exist.
