Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538702, here are decompositions:

31 + 31538671 = 31538702
61 + 31538641 = 31538702
73 + 31538629 = 31538702
79 + 31538623 = 31538702
163 + 31538539 = 31538702
199 + 31538503 = 31538702
211 + 31538491 = 31538702
229 + 31538473 = 31538702

Showing the first eight; more decompositions exist.
