Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479086, here are decompositions:

3 + 31479083 = 31479086
13 + 31479073 = 31479086
103 + 31478983 = 31479086
127 + 31478959 = 31479086
349 + 31478737 = 31479086
367 + 31478719 = 31479086
439 + 31478647 = 31479086
487 + 31478599 = 31479086

Showing the first eight; more decompositions exist.
