Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480962, here are decompositions:

13 + 31480949 = 31480962
43 + 31480919 = 31480962
61 + 31480901 = 31480962
83 + 31480879 = 31480962
89 + 31480873 = 31480962
101 + 31480861 = 31480962
113 + 31480849 = 31480962
193 + 31480769 = 31480962

Showing the first eight; more decompositions exist.
