Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476688, here are decompositions:

101 + 31476587 = 31476688
137 + 31476551 = 31476688
179 + 31476509 = 31476688
227 + 31476461 = 31476688
239 + 31476449 = 31476688
251 + 31476437 = 31476688
317 + 31476371 = 31476688
449 + 31476239 = 31476688

Showing the first eight; more decompositions exist.
