Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31485962, here are decompositions:

3 + 31485959 = 31485962
31 + 31485931 = 31485962
73 + 31485889 = 31485962
139 + 31485823 = 31485962
163 + 31485799 = 31485962
241 + 31485721 = 31485962
379 + 31485583 = 31485962
421 + 31485541 = 31485962

Showing the first eight; more decompositions exist.
