Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611462, here are decompositions:

5 + 31611457 = 31611462
23 + 31611439 = 31611462
59 + 31611403 = 31611462
83 + 31611379 = 31611462
139 + 31611323 = 31611462
151 + 31611311 = 31611462
163 + 31611299 = 31611462
191 + 31611271 = 31611462

Showing the first eight; more decompositions exist.
