Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574762, here are decompositions:

61 + 31574701 = 31574762
73 + 31574689 = 31574762
199 + 31574563 = 31574762
283 + 31574479 = 31574762
313 + 31574449 = 31574762
433 + 31574329 = 31574762
631 + 31574131 = 31574762
691 + 31574071 = 31574762

Showing the first eight; more decompositions exist.
