Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461958, here are decompositions:

71 + 31461887 = 31461958
107 + 31461851 = 31461958
167 + 31461791 = 31461958
179 + 31461779 = 31461958
197 + 31461761 = 31461958
317 + 31461641 = 31461958
389 + 31461569 = 31461958
401 + 31461557 = 31461958

Showing the first eight; more decompositions exist.
