Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462916, here are decompositions:

7 + 31462909 = 31462916
19 + 31462897 = 31462916
109 + 31462807 = 31462916
157 + 31462759 = 31462916
193 + 31462723 = 31462916
307 + 31462609 = 31462916
313 + 31462603 = 31462916
337 + 31462579 = 31462916

Showing the first eight; more decompositions exist.
