Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606524, here are decompositions:

7 + 31606517 = 31606524
31 + 31606493 = 31606524
101 + 31606423 = 31606524
113 + 31606411 = 31606524
127 + 31606397 = 31606524
137 + 31606387 = 31606524
151 + 31606373 = 31606524
181 + 31606343 = 31606524

Showing the first eight; more decompositions exist.
