Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541162, here are decompositions:

61 + 31541101 = 31541162
223 + 31540939 = 31541162
241 + 31540921 = 31541162
349 + 31540813 = 31541162
379 + 31540783 = 31541162
439 + 31540723 = 31541162
463 + 31540699 = 31541162
661 + 31540501 = 31541162

Showing the first eight; more decompositions exist.
