Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494904, here are decompositions:

17 + 31494887 = 31494904
137 + 31494767 = 31494904
167 + 31494737 = 31494904
191 + 31494713 = 31494904
197 + 31494707 = 31494904
293 + 31494611 = 31494904
401 + 31494503 = 31494904
461 + 31494443 = 31494904

Showing the first eight; more decompositions exist.
