Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494832, here are decompositions:

23 + 31494809 = 31494832
251 + 31494581 = 31494832
353 + 31494479 = 31494832
389 + 31494443 = 31494832
401 + 31494431 = 31494832
431 + 31494401 = 31494832
443 + 31494389 = 31494832
569 + 31494263 = 31494832

Showing the first eight; more decompositions exist.
