Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31606718, here are decompositions:

7 + 31606711 = 31606718
37 + 31606681 = 31606718
61 + 31606657 = 31606718
67 + 31606651 = 31606718
139 + 31606579 = 31606718
181 + 31606537 = 31606718
307 + 31606411 = 31606718
331 + 31606387 = 31606718

Showing the first eight; more decompositions exist.
