Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465206, here are decompositions:

13 + 31465193 = 31465206
23 + 31465183 = 31465206
29 + 31465177 = 31465206
53 + 31465153 = 31465206
83 + 31465123 = 31465206
107 + 31465099 = 31465206
137 + 31465069 = 31465206
167 + 31465039 = 31465206

Showing the first eight; more decompositions exist.
