Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31548626, here are decompositions:

7 + 31548619 = 31548626
13 + 31548613 = 31548626
79 + 31548547 = 31548626
127 + 31548499 = 31548626
199 + 31548427 = 31548626
283 + 31548343 = 31548626
313 + 31548313 = 31548626
523 + 31548103 = 31548626

Showing the first eight; more decompositions exist.
