Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611450, here are decompositions:

11 + 31611439 = 31611450
47 + 31611403 = 31611450
71 + 31611379 = 31611450
83 + 31611367 = 31611450
109 + 31611341 = 31611450
127 + 31611323 = 31611450
131 + 31611319 = 31611450
139 + 31611311 = 31611450

Showing the first eight; more decompositions exist.
