Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541908, here are decompositions:

5 + 31541903 = 31541908
17 + 31541891 = 31541908
257 + 31541651 = 31541908
311 + 31541597 = 31541908
317 + 31541591 = 31541908
401 + 31541507 = 31541908
479 + 31541429 = 31541908
491 + 31541417 = 31541908

Showing the first eight; more decompositions exist.
