Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540764, here are decompositions:

37 + 31540727 = 31540764
41 + 31540723 = 31540764
71 + 31540693 = 31540764
107 + 31540657 = 31540764
113 + 31540651 = 31540764
127 + 31540637 = 31540764
191 + 31540573 = 31540764
263 + 31540501 = 31540764

Showing the first eight; more decompositions exist.
