Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479266, here are decompositions:

139 + 31479127 = 31479266
193 + 31479073 = 31479266
283 + 31478983 = 31479266
307 + 31478959 = 31479266
547 + 31478719 = 31479266
619 + 31478647 = 31479266
673 + 31478593 = 31479266
787 + 31478479 = 31479266

Showing the first eight; more decompositions exist.
