Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606358, here are decompositions:

19 + 31606339 = 31606358
61 + 31606297 = 31606358
79 + 31606279 = 31606358
97 + 31606261 = 31606358
271 + 31606087 = 31606358
307 + 31606051 = 31606358
547 + 31605811 = 31606358
577 + 31605781 = 31606358

Showing the first eight; more decompositions exist.
