Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468186, here are decompositions:

17 + 31468169 = 31468186
89 + 31468097 = 31468186
173 + 31468013 = 31468186
293 + 31467893 = 31468186
419 + 31467767 = 31468186
467 + 31467719 = 31468186
509 + 31467677 = 31468186
593 + 31467593 = 31468186

Showing the first eight; more decompositions exist.
