Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494808, here are decompositions:

41 + 31494767 = 31494808
71 + 31494737 = 31494808
101 + 31494707 = 31494808
197 + 31494611 = 31494808
227 + 31494581 = 31494808
311 + 31494497 = 31494808
419 + 31494389 = 31494808
461 + 31494347 = 31494808

Showing the first eight; more decompositions exist.
