Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461082, here are decompositions:

71 + 31461011 = 31461082
131 + 31460951 = 31461082
251 + 31460831 = 31461082
353 + 31460729 = 31461082
599 + 31460483 = 31461082
641 + 31460441 = 31461082
683 + 31460399 = 31461082
743 + 31460339 = 31461082

Showing the first eight; more decompositions exist.
