Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611626, here are decompositions:

19 + 31611607 = 31611626
43 + 31611583 = 31611626
73 + 31611553 = 31611626
139 + 31611487 = 31611626
223 + 31611403 = 31611626
307 + 31611319 = 31611626
439 + 31611187 = 31611626
463 + 31611163 = 31611626

Showing the first eight; more decompositions exist.
