Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465048, here are decompositions:

101 + 31464947 = 31465048
107 + 31464941 = 31465048
227 + 31464821 = 31465048
239 + 31464809 = 31465048
317 + 31464731 = 31465048
347 + 31464701 = 31465048
431 + 31464617 = 31465048
467 + 31464581 = 31465048

Showing the first eight; more decompositions exist.
