Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458684, here are decompositions:

17 + 31458667 = 31458684
41 + 31458643 = 31458684
53 + 31458631 = 31458684
83 + 31458601 = 31458684
97 + 31458587 = 31458684
157 + 31458527 = 31458684
197 + 31458487 = 31458684
233 + 31458451 = 31458684

Showing the first eight; more decompositions exist.
