Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31571714, here are decompositions:

7 + 31571707 = 31571714
61 + 31571653 = 31571714
67 + 31571647 = 31571714
103 + 31571611 = 31571714
157 + 31571557 = 31571714
277 + 31571437 = 31571714
331 + 31571383 = 31571714
367 + 31571347 = 31571714

Showing the first eight; more decompositions exist.
