Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606170, here are decompositions:

73 + 31606097 = 31606170
83 + 31606087 = 31606170
103 + 31606067 = 31606170
109 + 31606061 = 31606170
199 + 31605971 = 31606170
241 + 31605929 = 31606170
257 + 31605913 = 31606170
293 + 31605877 = 31606170

Showing the first eight; more decompositions exist.
