Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494224, here are decompositions:

67 + 31494157 = 31494224
127 + 31494097 = 31494224
241 + 31493983 = 31494224
283 + 31493941 = 31494224
367 + 31493857 = 31494224
373 + 31493851 = 31494224
547 + 31493677 = 31494224
571 + 31493653 = 31494224

Showing the first eight; more decompositions exist.
