Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606418, here are decompositions:

7 + 31606411 = 31606418
31 + 31606387 = 31606418
37 + 31606381 = 31606418
79 + 31606339 = 31606418
139 + 31606279 = 31606418
157 + 31606261 = 31606418
331 + 31606087 = 31606418
367 + 31606051 = 31606418

Showing the first eight; more decompositions exist.
