Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506714, here are decompositions:

17 + 31506697 = 31506714
37 + 31506677 = 31506714
73 + 31506641 = 31506714
137 + 31506577 = 31506714
191 + 31506523 = 31506714
193 + 31506521 = 31506714
271 + 31506443 = 31506714
277 + 31506437 = 31506714

Showing the first eight; more decompositions exist.
