Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31537962, here are decompositions:

23 + 31537939 = 31537962
41 + 31537921 = 31537962
59 + 31537903 = 31537962
73 + 31537889 = 31537962
101 + 31537861 = 31537962
103 + 31537859 = 31537962
139 + 31537823 = 31537962
241 + 31537721 = 31537962

Showing the first eight; more decompositions exist.
