Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456192, here are decompositions:

29 + 31456163 = 31456192
71 + 31456121 = 31456192
113 + 31456079 = 31456192
179 + 31456013 = 31456192
233 + 31455959 = 31456192
263 + 31455929 = 31456192
389 + 31455803 = 31456192
431 + 31455761 = 31456192

Showing the first eight; more decompositions exist.
