Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31627684, here are decompositions:

83 + 31627601 = 31627684
107 + 31627577 = 31627684
173 + 31627511 = 31627684
293 + 31627391 = 31627684
311 + 31627373 = 31627684
467 + 31627217 = 31627684
563 + 31627121 = 31627684
593 + 31627091 = 31627684

Showing the first eight; more decompositions exist.
