Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611476, here are decompositions:

3 + 31611473 = 31611476
19 + 31611457 = 31611476
37 + 31611439 = 31611476
73 + 31611403 = 31611476
97 + 31611379 = 31611476
109 + 31611367 = 31611476
157 + 31611319 = 31611476
313 + 31611163 = 31611476

Showing the first eight; more decompositions exist.
