Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479056, here are decompositions:

73 + 31478983 = 31479056
97 + 31478959 = 31479056
337 + 31478719 = 31479056
409 + 31478647 = 31479056
457 + 31478599 = 31479056
463 + 31478593 = 31479056
577 + 31478479 = 31479056
733 + 31478323 = 31479056

Showing the first eight; more decompositions exist.
