Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611632, here are decompositions:

79 + 31611553 = 31611632
193 + 31611439 = 31611632
229 + 31611403 = 31611632
313 + 31611319 = 31611632
331 + 31611301 = 31611632
739 + 31610893 = 31611632
853 + 31610779 = 31611632
859 + 31610773 = 31611632

Showing the first eight; more decompositions exist.
