Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606204, here are decompositions:

17 + 31606187 = 31606204
23 + 31606181 = 31606204
107 + 31606097 = 31606204
137 + 31606067 = 31606204
233 + 31605971 = 31606204
251 + 31605953 = 31606204
401 + 31605803 = 31606204
431 + 31605773 = 31606204

Showing the first eight; more decompositions exist.
