Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606042, here are decompositions:

59 + 31605983 = 31606042
71 + 31605971 = 31606042
89 + 31605953 = 31606042
113 + 31605929 = 31606042
233 + 31605809 = 31606042
239 + 31605803 = 31606042
263 + 31605779 = 31606042
269 + 31605773 = 31606042

Showing the first eight; more decompositions exist.
