Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465198, here are decompositions:

5 + 31465193 = 31465198
137 + 31465061 = 31465198
251 + 31464947 = 31465198
257 + 31464941 = 31465198
389 + 31464809 = 31465198
467 + 31464731 = 31465198
617 + 31464581 = 31465198
641 + 31464557 = 31465198

Showing the first eight; more decompositions exist.
