Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540562, here are decompositions:

61 + 31540501 = 31540562
73 + 31540489 = 31540562
199 + 31540363 = 31540562
223 + 31540339 = 31540562
349 + 31540213 = 31540562
373 + 31540189 = 31540562
439 + 31540123 = 31540562
463 + 31540099 = 31540562

Showing the first eight; more decompositions exist.
