Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476724, here are decompositions:

101 + 31476623 = 31476724
113 + 31476611 = 31476724
131 + 31476593 = 31476724
137 + 31476587 = 31476724
173 + 31476551 = 31476724
263 + 31476461 = 31476724
311 + 31476413 = 31476724
353 + 31476371 = 31476724

Showing the first eight; more decompositions exist.
