Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606746, here are decompositions:

5 + 31606741 = 31606746
19 + 31606727 = 31606746
43 + 31606703 = 31606746
79 + 31606667 = 31606746
89 + 31606657 = 31606746
103 + 31606643 = 31606746
163 + 31606583 = 31606746
167 + 31606579 = 31606746

Showing the first eight; more decompositions exist.
