Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31465236, here are decompositions:

13 + 31465223 = 31465236
43 + 31465193 = 31465236
53 + 31465183 = 31465236
59 + 31465177 = 31465236
83 + 31465153 = 31465236
107 + 31465129 = 31465236
113 + 31465123 = 31465236
137 + 31465099 = 31465236

Showing the first eight; more decompositions exist.
