Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456862, here are decompositions:

13 + 31456849 = 31456862
43 + 31456819 = 31456862
193 + 31456669 = 31456862
211 + 31456651 = 31456862
223 + 31456639 = 31456862
331 + 31456531 = 31456862
421 + 31456441 = 31456862
433 + 31456429 = 31456862

Showing the first eight; more decompositions exist.
