Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606506, here are decompositions:

7 + 31606499 = 31606506
13 + 31606493 = 31606506
37 + 31606469 = 31606506
83 + 31606423 = 31606506
109 + 31606397 = 31606506
137 + 31606369 = 31606506
163 + 31606343 = 31606506
167 + 31606339 = 31606506

Showing the first eight; more decompositions exist.
