Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607002, here are decompositions:

5 + 31606997 = 31607002
23 + 31606979 = 31607002
29 + 31606973 = 31607002
59 + 31606943 = 31607002
71 + 31606931 = 31607002
83 + 31606919 = 31607002
173 + 31606829 = 31607002
191 + 31606811 = 31607002

Showing the first eight; more decompositions exist.
