Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611432, here are decompositions:

29 + 31611403 = 31611432
53 + 31611379 = 31611432
103 + 31611329 = 31611432
109 + 31611323 = 31611432
113 + 31611319 = 31611432
131 + 31611301 = 31611432
269 + 31611163 = 31611432
331 + 31611101 = 31611432

Showing the first eight; more decompositions exist.
