Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456850, here are decompositions:

31 + 31456819 = 31456850
109 + 31456741 = 31456850
181 + 31456669 = 31456850
199 + 31456651 = 31456850
211 + 31456639 = 31456850
349 + 31456501 = 31456850
409 + 31456441 = 31456850
421 + 31456429 = 31456850

Showing the first eight; more decompositions exist.
