Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506710, here are decompositions:

13 + 31506697 = 31506710
181 + 31506529 = 31506710
199 + 31506511 = 31506710
337 + 31506373 = 31506710
379 + 31506331 = 31506710
439 + 31506271 = 31506710
463 + 31506247 = 31506710
607 + 31506103 = 31506710

Showing the first eight; more decompositions exist.
