Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574876, here are decompositions:

13 + 31574863 = 31574876
97 + 31574779 = 31574876
103 + 31574773 = 31574876
199 + 31574677 = 31574876
313 + 31574563 = 31574876
379 + 31574497 = 31574876
397 + 31574479 = 31574876
409 + 31574467 = 31574876

Showing the first eight; more decompositions exist.
