Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31468198, here are decompositions:

29 + 31468169 = 31468198
101 + 31468097 = 31468198
131 + 31468067 = 31468198
197 + 31468001 = 31468198
389 + 31467809 = 31468198
431 + 31467767 = 31468198
479 + 31467719 = 31468198
521 + 31467677 = 31468198

Showing the first eight; more decompositions exist.
