Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606050, here are decompositions:

67 + 31605983 = 31606050
79 + 31605971 = 31606050
97 + 31605953 = 31606050
137 + 31605913 = 31606050
173 + 31605877 = 31606050
227 + 31605823 = 31606050
239 + 31605811 = 31606050
241 + 31605809 = 31606050

Showing the first eight; more decompositions exist.
