Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465170, here are decompositions:

17 + 31465153 = 31465170
41 + 31465129 = 31465170
47 + 31465123 = 31465170
59 + 31465111 = 31465170
71 + 31465099 = 31465170
101 + 31465069 = 31465170
109 + 31465061 = 31465170
131 + 31465039 = 31465170

Showing the first eight; more decompositions exist.
