Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494712, here are decompositions:

5 + 31494707 = 31494712
23 + 31494689 = 31494712
101 + 31494611 = 31494712
131 + 31494581 = 31494712
233 + 31494479 = 31494712
269 + 31494443 = 31494712
281 + 31494431 = 31494712
311 + 31494401 = 31494712

Showing the first eight; more decompositions exist.
