Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461084, here are decompositions:

37 + 31461047 = 31461084
47 + 31461037 = 31461084
71 + 31461013 = 31461084
73 + 31461011 = 31461084
107 + 31460977 = 31461084
113 + 31460971 = 31461084
157 + 31460927 = 31461084
167 + 31460917 = 31461084

Showing the first eight; more decompositions exist.
