Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628056, here are decompositions:

107 + 31627949 = 31628056
167 + 31627889 = 31628056
263 + 31627793 = 31628056
293 + 31627763 = 31628056
479 + 31627577 = 31628056
683 + 31627373 = 31628056
809 + 31627247 = 31628056
839 + 31627217 = 31628056

Showing the first eight; more decompositions exist.
