Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553594, here are decompositions:

67 + 31553527 = 31553594
211 + 31553383 = 31553594
433 + 31553161 = 31553594
577 + 31553017 = 31553594
991 + 31552603 = 31553594
1201 + 31552393 = 31553594
1291 + 31552303 = 31553594
1597 + 31551997 = 31553594

Showing the first eight; more decompositions exist.
