Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540046, here are decompositions:

37 + 31540009 = 31540046
79 + 31539967 = 31540046
157 + 31539889 = 31540046
229 + 31539817 = 31540046
283 + 31539763 = 31540046
397 + 31539649 = 31540046
463 + 31539583 = 31540046
523 + 31539523 = 31540046

Showing the first eight; more decompositions exist.
