Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606094, here are decompositions:

7 + 31606087 = 31606094
43 + 31606051 = 31606094
181 + 31605913 = 31606094
271 + 31605823 = 31606094
283 + 31605811 = 31606094
313 + 31605781 = 31606094
337 + 31605757 = 31606094
367 + 31605727 = 31606094

Showing the first eight; more decompositions exist.
