Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454794, here are decompositions:

11 + 31454783 = 31454794
53 + 31454741 = 31454794
113 + 31454681 = 31454794
167 + 31454627 = 31454794
281 + 31454513 = 31454794
311 + 31454483 = 31454794
353 + 31454441 = 31454794
443 + 31454351 = 31454794

Showing the first eight; more decompositions exist.
