Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519352, here are decompositions:

31 + 31519321 = 31519352
211 + 31519141 = 31519352
283 + 31519069 = 31519352
439 + 31518913 = 31519352
661 + 31518691 = 31519352
751 + 31518601 = 31519352
811 + 31518541 = 31519352
829 + 31518523 = 31519352

Showing the first eight; more decompositions exist.
