Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611446, here are decompositions:

7 + 31611439 = 31611446
43 + 31611403 = 31611446
67 + 31611379 = 31611446
79 + 31611367 = 31611446
127 + 31611319 = 31611446
283 + 31611163 = 31611446
379 + 31611067 = 31611446
397 + 31611049 = 31611446

Showing the first eight; more decompositions exist.
