Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541476, here are decompositions:

47 + 31541429 = 31541476
59 + 31541417 = 31541476
179 + 31541297 = 31541476
233 + 31541243 = 31541476
347 + 31541129 = 31541476
359 + 31541117 = 31541476
653 + 31540823 = 31541476
797 + 31540679 = 31541476

Showing the first eight; more decompositions exist.
