Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494532, here are decompositions:

23 + 31494509 = 31494532
29 + 31494503 = 31494532
53 + 31494479 = 31494532
89 + 31494443 = 31494532
101 + 31494431 = 31494532
131 + 31494401 = 31494532
239 + 31494293 = 31494532
269 + 31494263 = 31494532

Showing the first eight; more decompositions exist.
