Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606368, here are decompositions:

29 + 31606339 = 31606368
37 + 31606331 = 31606368
71 + 31606297 = 31606368
89 + 31606279 = 31606368
107 + 31606261 = 31606368
181 + 31606187 = 31606368
271 + 31606097 = 31606368
281 + 31606087 = 31606368

Showing the first eight; more decompositions exist.
