Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456962, here are decompositions:

13 + 31456949 = 31456962
59 + 31456903 = 31456962
71 + 31456891 = 31456962
79 + 31456883 = 31456962
113 + 31456849 = 31456962
181 + 31456781 = 31456962
193 + 31456769 = 31456962
223 + 31456739 = 31456962

Showing the first eight; more decompositions exist.
