Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456952, here are decompositions:

3 + 31456949 = 31456952
61 + 31456891 = 31456952
103 + 31456849 = 31456952
211 + 31456741 = 31456952
283 + 31456669 = 31456952
313 + 31456639 = 31456952
421 + 31456531 = 31456952
523 + 31456429 = 31456952

Showing the first eight; more decompositions exist.
