Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611480, here are decompositions:

7 + 31611473 = 31611480
13 + 31611467 = 31611480
23 + 31611457 = 31611480
41 + 31611439 = 31611480
101 + 31611379 = 31611480
113 + 31611367 = 31611480
139 + 31611341 = 31611480
151 + 31611329 = 31611480

Showing the first eight; more decompositions exist.
