Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495102, here are decompositions:

59 + 31495043 = 31495102
83 + 31495019 = 31495102
179 + 31494923 = 31495102
293 + 31494809 = 31495102
389 + 31494713 = 31495102
491 + 31494611 = 31495102
521 + 31494581 = 31495102
593 + 31494509 = 31495102

Showing the first eight; more decompositions exist.
