Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454744, here are decompositions:

3 + 31454741 = 31454744
7 + 31454737 = 31454744
43 + 31454701 = 31454744
157 + 31454587 = 31454744
283 + 31454461 = 31454744
313 + 31454431 = 31454744
367 + 31454377 = 31454744
523 + 31454221 = 31454744

Showing the first eight; more decompositions exist.
