Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606084, here are decompositions:

5 + 31606079 = 31606084
17 + 31606067 = 31606084
23 + 31606061 = 31606084
101 + 31605983 = 31606084
113 + 31605971 = 31606084
131 + 31605953 = 31606084
281 + 31605803 = 31606084
311 + 31605773 = 31606084

Showing the first eight; more decompositions exist.
