Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547714, here are decompositions:

7 + 31547707 = 31547714
13 + 31547701 = 31547714
31 + 31547683 = 31547714
43 + 31547671 = 31547714
73 + 31547641 = 31547714
97 + 31547617 = 31547714
157 + 31547557 = 31547714
397 + 31547317 = 31547714

Showing the first eight; more decompositions exist.
