Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448710, here are decompositions:

3 + 31448707 = 31448710
11 + 31448699 = 31448710
17 + 31448693 = 31448710
71 + 31448639 = 31448710
89 + 31448621 = 31448710
107 + 31448603 = 31448710
131 + 31448579 = 31448710
191 + 31448519 = 31448710

Showing the first eight; more decompositions exist.
