Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31538726, here are decompositions:

7 + 31538719 = 31538726
13 + 31538713 = 31538726
73 + 31538653 = 31538726
97 + 31538629 = 31538726
103 + 31538623 = 31538726
157 + 31538569 = 31538726
199 + 31538527 = 31538726
223 + 31538503 = 31538726

Showing the first eight; more decompositions exist.
