Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448684, here are decompositions:

37 + 31448647 = 31448684
97 + 31448587 = 31448684
103 + 31448581 = 31448684
151 + 31448533 = 31448684
271 + 31448413 = 31448684
307 + 31448377 = 31448684
523 + 31448161 = 31448684
613 + 31448071 = 31448684

Showing the first eight; more decompositions exist.
