Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611330, here are decompositions:

7 + 31611323 = 31611330
11 + 31611319 = 31611330
19 + 31611311 = 31611330
29 + 31611301 = 31611330
31 + 31611299 = 31611330
59 + 31611271 = 31611330
167 + 31611163 = 31611330
193 + 31611137 = 31611330

Showing the first eight; more decompositions exist.
