Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31529046, here are decompositions:

53 + 31528993 = 31529046
79 + 31528967 = 31529046
137 + 31528909 = 31529046
193 + 31528853 = 31529046
223 + 31528823 = 31529046
233 + 31528813 = 31529046
239 + 31528807 = 31529046
317 + 31528729 = 31529046

Showing the first eight; more decompositions exist.
