Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606500, here are decompositions:

7 + 31606493 = 31606500
31 + 31606469 = 31606500
71 + 31606429 = 31606500
89 + 31606411 = 31606500
103 + 31606397 = 31606500
113 + 31606387 = 31606500
127 + 31606373 = 31606500
131 + 31606369 = 31606500

Showing the first eight; more decompositions exist.
