Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31519754, here are decompositions:

43 + 31519711 = 31519754
67 + 31519687 = 31519754
223 + 31519531 = 31519754
271 + 31519483 = 31519754
313 + 31519441 = 31519754
337 + 31519417 = 31519754
373 + 31519381 = 31519754
397 + 31519357 = 31519754

Showing the first eight; more decompositions exist.
