Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458632, here are decompositions:

31 + 31458601 = 31458632
43 + 31458589 = 31458632
151 + 31458481 = 31458632
181 + 31458451 = 31458632
229 + 31458403 = 31458632
463 + 31458169 = 31458632
571 + 31458061 = 31458632
619 + 31458013 = 31458632

Showing the first eight; more decompositions exist.
