Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476550, here are decompositions:

3 + 31476547 = 31476550
41 + 31476509 = 31476550
89 + 31476461 = 31476550
101 + 31476449 = 31476550
113 + 31476437 = 31476550
137 + 31476413 = 31476550
167 + 31476383 = 31476550
179 + 31476371 = 31476550

Showing the first eight; more decompositions exist.
