Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461868, here are decompositions:

17 + 31461851 = 31461868
89 + 31461779 = 31461868
107 + 31461761 = 31461868
131 + 31461737 = 31461868
227 + 31461641 = 31461868
311 + 31461557 = 31461868
587 + 31461281 = 31461868
677 + 31461191 = 31461868

Showing the first eight; more decompositions exist.
