Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588506, here are decompositions:

13 + 31588493 = 31588506
23 + 31588483 = 31588506
43 + 31588463 = 31588506
67 + 31588439 = 31588506
107 + 31588399 = 31588506
137 + 31588369 = 31588506
139 + 31588367 = 31588506
149 + 31588357 = 31588506

Showing the first eight; more decompositions exist.
