Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495462, here are decompositions:

59 + 31495403 = 31495462
101 + 31495361 = 31495462
263 + 31495199 = 31495462
353 + 31495109 = 31495462
419 + 31495043 = 31495462
443 + 31495019 = 31495462
653 + 31494809 = 31495462
773 + 31494689 = 31495462

Showing the first eight; more decompositions exist.
