Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461042, here are decompositions:

5 + 31461037 = 31461042
29 + 31461013 = 31461042
31 + 31461011 = 31461042
71 + 31460971 = 31461042
113 + 31460929 = 31461042
163 + 31460879 = 31461042
191 + 31460851 = 31461042
211 + 31460831 = 31461042

Showing the first eight; more decompositions exist.
