Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519484, here are decompositions:

43 + 31519441 = 31519484
67 + 31519417 = 31519484
103 + 31519381 = 31519484
127 + 31519357 = 31519484
163 + 31519321 = 31519484
523 + 31518961 = 31519484
571 + 31518913 = 31519484
691 + 31518793 = 31519484

Showing the first eight; more decompositions exist.
