Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458832, here are decompositions:

3 + 31458829 = 31458832
11 + 31458821 = 31458832
71 + 31458761 = 31458832
113 + 31458719 = 31458832
131 + 31458701 = 31458832
239 + 31458593 = 31458832
401 + 31458431 = 31458832
521 + 31458311 = 31458832

Showing the first eight; more decompositions exist.
