Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496086, here are decompositions:

3 + 31496083 = 31496086
29 + 31496057 = 31496086
59 + 31496027 = 31496086
107 + 31495979 = 31496086
137 + 31495949 = 31496086
227 + 31495859 = 31496086
239 + 31495847 = 31496086
353 + 31495733 = 31496086

Showing the first eight; more decompositions exist.
