Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494898, here are decompositions:

11 + 31494887 = 31494898
89 + 31494809 = 31494898
131 + 31494767 = 31494898
191 + 31494707 = 31494898
317 + 31494581 = 31494898
389 + 31494509 = 31494898
401 + 31494497 = 31494898
419 + 31494479 = 31494898

Showing the first eight; more decompositions exist.
