Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31607436, here are decompositions:

13 + 31607423 = 31607436
37 + 31607399 = 31607436
73 + 31607363 = 31607436
79 + 31607357 = 31607436
109 + 31607327 = 31607436
127 + 31607309 = 31607436
137 + 31607299 = 31607436
139 + 31607297 = 31607436

Showing the first eight; more decompositions exist.
