Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542350, here are decompositions:

283 + 31542067 = 31542350
313 + 31542037 = 31542350
337 + 31542013 = 31542350
349 + 31542001 = 31542350
373 + 31541977 = 31542350
379 + 31541971 = 31542350
457 + 31541893 = 31542350
523 + 31541827 = 31542350

Showing the first eight; more decompositions exist.
