Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541416, here are decompositions:

17 + 31541399 = 31541416
149 + 31541267 = 31541416
173 + 31541243 = 31541416
593 + 31540823 = 31541416
773 + 31540643 = 31541416
887 + 31540529 = 31541416
1307 + 31540109 = 31541416
1409 + 31540007 = 31541416

Showing the first eight; more decompositions exist.
