Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458862, here are decompositions:

41 + 31458821 = 31458862
101 + 31458761 = 31458862
173 + 31458689 = 31458862
269 + 31458593 = 31458862
431 + 31458431 = 31458862
443 + 31458419 = 31458862
563 + 31458299 = 31458862
863 + 31457999 = 31458862

Showing the first eight; more decompositions exist.
