Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606002, here are decompositions:

19 + 31605983 = 31606002
31 + 31605971 = 31606002
73 + 31605929 = 31606002
89 + 31605913 = 31606002
179 + 31605823 = 31606002
191 + 31605811 = 31606002
193 + 31605809 = 31606002
199 + 31605803 = 31606002

Showing the first eight; more decompositions exist.
