Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607406, here are decompositions:

7 + 31607399 = 31607406
43 + 31607363 = 31607406
79 + 31607327 = 31607406
97 + 31607309 = 31607406
107 + 31607299 = 31607406
109 + 31607297 = 31607406
113 + 31607293 = 31607406
179 + 31607227 = 31607406

Showing the first eight; more decompositions exist.
