Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574798, here are decompositions:

19 + 31574779 = 31574798
97 + 31574701 = 31574798
109 + 31574689 = 31574798
127 + 31574671 = 31574798
331 + 31574467 = 31574798
349 + 31574449 = 31574798
379 + 31574419 = 31574798
691 + 31574107 = 31574798

Showing the first eight; more decompositions exist.
