Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606546, here are decompositions:

3 + 31606543 = 31606546
5 + 31606541 = 31606546
17 + 31606529 = 31606546
29 + 31606517 = 31606546
47 + 31606499 = 31606546
53 + 31606493 = 31606546
149 + 31606397 = 31606546
173 + 31606373 = 31606546

Showing the first eight; more decompositions exist.
