Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461038, here are decompositions:

31 + 31461007 = 31461038
61 + 31460977 = 31461038
67 + 31460971 = 31461038
109 + 31460929 = 31461038
199 + 31460839 = 31461038
229 + 31460809 = 31461038
337 + 31460701 = 31461038
457 + 31460581 = 31461038

Showing the first eight; more decompositions exist.
