Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448766, here are decompositions:

47 + 31448719 = 31448766
53 + 31448713 = 31448766
59 + 31448707 = 31448766
67 + 31448699 = 31448766
73 + 31448693 = 31448766
127 + 31448639 = 31448766
163 + 31448603 = 31448766
179 + 31448587 = 31448766

Showing the first eight; more decompositions exist.
