Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606100, here are decompositions:

3 + 31606097 = 31606100
13 + 31606087 = 31606100
223 + 31605877 = 31606100
277 + 31605823 = 31606100
373 + 31605727 = 31606100
523 + 31605577 = 31606100
661 + 31605439 = 31606100
739 + 31605361 = 31606100

Showing the first eight; more decompositions exist.
