Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533626, here are decompositions:

13 + 31533613 = 31533626
79 + 31533547 = 31533626
109 + 31533517 = 31533626
127 + 31533499 = 31533626
283 + 31533343 = 31533626
367 + 31533259 = 31533626
499 + 31533127 = 31533626
613 + 31533013 = 31533626

Showing the first eight; more decompositions exist.
