Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606850, here are decompositions:

3 + 31606847 = 31606850
97 + 31606753 = 31606850
109 + 31606741 = 31606850
139 + 31606711 = 31606850
193 + 31606657 = 31606850
199 + 31606651 = 31606850
271 + 31606579 = 31606850
307 + 31606543 = 31606850

Showing the first eight; more decompositions exist.
