Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586346, here are decompositions:

7 + 31586339 = 31586346
59 + 31586287 = 31586346
73 + 31586273 = 31586346
89 + 31586257 = 31586346
109 + 31586237 = 31586346
199 + 31586147 = 31586346
269 + 31586077 = 31586346
293 + 31586053 = 31586346

Showing the first eight; more decompositions exist.
