Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465684, here are decompositions:

11 + 31465673 = 31465684
23 + 31465661 = 31465684
53 + 31465631 = 31465684
83 + 31465601 = 31465684
113 + 31465571 = 31465684
137 + 31465547 = 31465684
233 + 31465451 = 31465684
293 + 31465391 = 31465684

Showing the first eight; more decompositions exist.
