Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540976, here are decompositions:

37 + 31540939 = 31540976
109 + 31540867 = 31540976
139 + 31540837 = 31540976
163 + 31540813 = 31540976
193 + 31540783 = 31540976
277 + 31540699 = 31540976
283 + 31540693 = 31540976
307 + 31540669 = 31540976

Showing the first eight; more decompositions exist.
