Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626506, here are decompositions:

7 + 31626499 = 31626506
13 + 31626493 = 31626506
139 + 31626367 = 31626506
277 + 31626229 = 31626506
313 + 31626193 = 31626506
397 + 31626109 = 31626506
433 + 31626073 = 31626506
487 + 31626019 = 31626506

Showing the first eight; more decompositions exist.
