Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611602, here are decompositions:

19 + 31611583 = 31611602
163 + 31611439 = 31611602
199 + 31611403 = 31611602
223 + 31611379 = 31611602
283 + 31611319 = 31611602
331 + 31611271 = 31611602
439 + 31611163 = 31611602
691 + 31610911 = 31611602

Showing the first eight; more decompositions exist.
