Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456150, here are decompositions:

29 + 31456121 = 31456150
71 + 31456079 = 31456150
83 + 31456067 = 31456150
137 + 31456013 = 31456150
191 + 31455959 = 31456150
281 + 31455869 = 31456150
347 + 31455803 = 31456150
389 + 31455761 = 31456150

Showing the first eight; more decompositions exist.
