Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618962, here are decompositions:

13 + 31618949 = 31618962
19 + 31618943 = 31618962
61 + 31618901 = 31618962
71 + 31618891 = 31618962
79 + 31618883 = 31618962
83 + 31618879 = 31618962
113 + 31618849 = 31618962
139 + 31618823 = 31618962

Showing the first eight; more decompositions exist.
