Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486342, here are decompositions:

3 + 31486339 = 31486342
5 + 31486337 = 31486342
53 + 31486289 = 31486342
59 + 31486283 = 31486342
71 + 31486271 = 31486342
89 + 31486253 = 31486342
113 + 31486229 = 31486342
179 + 31486163 = 31486342

Showing the first eight; more decompositions exist.
