Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31460658, here are decompositions:

11 + 31460647 = 31460658
107 + 31460551 = 31460658
109 + 31460549 = 31460658
149 + 31460509 = 31460658
167 + 31460491 = 31460658
227 + 31460431 = 31460658
311 + 31460347 = 31460658
337 + 31460321 = 31460658

Showing the first eight; more decompositions exist.
