Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495910, here are decompositions:

13 + 31495897 = 31495910
31 + 31495879 = 31495910
109 + 31495801 = 31495910
157 + 31495753 = 31495910
181 + 31495729 = 31495910
307 + 31495603 = 31495910
409 + 31495501 = 31495910
463 + 31495447 = 31495910

Showing the first eight; more decompositions exist.
