Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463040, here are decompositions:

17 + 31463023 = 31463040
61 + 31462979 = 31463040
71 + 31462969 = 31463040
107 + 31462933 = 31463040
109 + 31462931 = 31463040
131 + 31462909 = 31463040
139 + 31462901 = 31463040
151 + 31462889 = 31463040

Showing the first eight; more decompositions exist.
