Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574846, here are decompositions:

67 + 31574779 = 31574846
73 + 31574773 = 31574846
157 + 31574689 = 31574846
283 + 31574563 = 31574846
349 + 31574497 = 31574846
367 + 31574479 = 31574846
379 + 31574467 = 31574846
397 + 31574449 = 31574846

Showing the first eight; more decompositions exist.
