Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606450, here are decompositions:

53 + 31606397 = 31606450
107 + 31606343 = 31606450
131 + 31606319 = 31606450
137 + 31606313 = 31606450
167 + 31606283 = 31606450
173 + 31606277 = 31606450
263 + 31606187 = 31606450
269 + 31606181 = 31606450

Showing the first eight; more decompositions exist.
