Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494802, here are decompositions:

89 + 31494713 = 31494802
113 + 31494689 = 31494802
191 + 31494611 = 31494802
293 + 31494509 = 31494802
359 + 31494443 = 31494802
401 + 31494401 = 31494802
509 + 31494293 = 31494802
641 + 31494161 = 31494802

Showing the first eight; more decompositions exist.
