Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31479010, here are decompositions:

41 + 31478969 = 31479010
53 + 31478957 = 31479010
179 + 31478831 = 31479010
443 + 31478567 = 31479010
599 + 31478411 = 31479010
617 + 31478393 = 31479010
659 + 31478351 = 31479010
677 + 31478333 = 31479010

Showing the first eight; more decompositions exist.
