Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519082, here are decompositions:

13 + 31519069 = 31519082
223 + 31518859 = 31519082
409 + 31518673 = 31519082
541 + 31518541 = 31519082
601 + 31518481 = 31519082
631 + 31518451 = 31519082
739 + 31518343 = 31519082
769 + 31518313 = 31519082

Showing the first eight; more decompositions exist.
