Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607066, here are decompositions:

19 + 31607047 = 31607066
103 + 31606963 = 31607066
109 + 31606957 = 31607066
163 + 31606903 = 31607066
313 + 31606753 = 31607066
409 + 31606657 = 31607066
487 + 31606579 = 31607066
523 + 31606543 = 31607066

Showing the first eight; more decompositions exist.
