Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495294, here are decompositions:

53 + 31495241 = 31495294
107 + 31495187 = 31495294
137 + 31495157 = 31495294
251 + 31495043 = 31495294
557 + 31494737 = 31495294
587 + 31494707 = 31495294
683 + 31494611 = 31495294
797 + 31494497 = 31495294

Showing the first eight; more decompositions exist.
