Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606132, here are decompositions:

53 + 31606079 = 31606132
71 + 31606061 = 31606132
83 + 31606049 = 31606132
149 + 31605983 = 31606132
179 + 31605953 = 31606132
353 + 31605779 = 31606132
359 + 31605773 = 31606132
419 + 31605713 = 31606132

Showing the first eight; more decompositions exist.
