Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461078, here are decompositions:

29 + 31461049 = 31461078
31 + 31461047 = 31461078
41 + 31461037 = 31461078
67 + 31461011 = 31461078
71 + 31461007 = 31461078
101 + 31460977 = 31461078
107 + 31460971 = 31461078
127 + 31460951 = 31461078

Showing the first eight; more decompositions exist.
