Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494754, here are decompositions:

17 + 31494737 = 31494754
41 + 31494713 = 31494754
47 + 31494707 = 31494754
173 + 31494581 = 31494754
251 + 31494503 = 31494754
257 + 31494497 = 31494754
311 + 31494443 = 31494754
353 + 31494401 = 31494754

Showing the first eight; more decompositions exist.
