Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479922, here are decompositions:

41 + 31479881 = 31479922
101 + 31479821 = 31479922
179 + 31479743 = 31479922
251 + 31479671 = 31479922
431 + 31479491 = 31479922
503 + 31479419 = 31479922
653 + 31479269 = 31479922
821 + 31479101 = 31479922

Showing the first eight; more decompositions exist.
