Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31476748, here are decompositions:

5 + 31476743 = 31476748
137 + 31476611 = 31476748
197 + 31476551 = 31476748
239 + 31476509 = 31476748
311 + 31476437 = 31476748
431 + 31476317 = 31476748
509 + 31476239 = 31476748
599 + 31476149 = 31476748

Showing the first eight; more decompositions exist.
