Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460690, here are decompositions:

13 + 31460677 = 31460690
43 + 31460647 = 31460690
109 + 31460581 = 31460690
139 + 31460551 = 31460690
181 + 31460509 = 31460690
193 + 31460497 = 31460690
199 + 31460491 = 31460690
277 + 31460413 = 31460690

Showing the first eight; more decompositions exist.
