Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540754, here are decompositions:

31 + 31540723 = 31540754
61 + 31540693 = 31540754
97 + 31540657 = 31540754
103 + 31540651 = 31540754
181 + 31540573 = 31540754
283 + 31540471 = 31540754
313 + 31540441 = 31540754
337 + 31540417 = 31540754

Showing the first eight; more decompositions exist.
