Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31458956, here are decompositions:

3 + 31458953 = 31458956
19 + 31458937 = 31458956
43 + 31458913 = 31458956
127 + 31458829 = 31458956
157 + 31458799 = 31458956
313 + 31458643 = 31458956
349 + 31458607 = 31458956
367 + 31458589 = 31458956

Showing the first eight; more decompositions exist.
