Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479026, here are decompositions:

43 + 31478983 = 31479026
67 + 31478959 = 31479026
307 + 31478719 = 31479026
379 + 31478647 = 31479026
433 + 31478593 = 31479026
547 + 31478479 = 31479026
739 + 31478287 = 31479026
853 + 31478173 = 31479026

Showing the first eight; more decompositions exist.
