Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495060, here are decompositions:

17 + 31495043 = 31495060
41 + 31495019 = 31495060
137 + 31494923 = 31495060
173 + 31494887 = 31495060
251 + 31494809 = 31495060
293 + 31494767 = 31495060
347 + 31494713 = 31495060
353 + 31494707 = 31495060

Showing the first eight; more decompositions exist.
