Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461736, here are decompositions:

83 + 31461653 = 31461736
167 + 31461569 = 31461736
179 + 31461557 = 31461736
443 + 31461293 = 31461736
557 + 31461179 = 31461736
563 + 31461173 = 31461736
587 + 31461149 = 31461736
809 + 31460927 = 31461736

Showing the first eight; more decompositions exist.
