Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611452, here are decompositions:

13 + 31611439 = 31611452
73 + 31611379 = 31611452
151 + 31611301 = 31611452
181 + 31611271 = 31611452
409 + 31611043 = 31611452
541 + 31610911 = 31611452
661 + 31610791 = 31611452
673 + 31610779 = 31611452

Showing the first eight; more decompositions exist.
