Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542454, here are decompositions:

17 + 31542437 = 31542454
113 + 31542341 = 31542454
131 + 31542323 = 31542454
173 + 31542281 = 31542454
257 + 31542197 = 31542454
431 + 31542023 = 31542454
443 + 31542011 = 31542454
521 + 31541933 = 31542454

Showing the first eight; more decompositions exist.
