Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553354, here are decompositions:

3 + 31553351 = 31553354
193 + 31553161 = 31553354
277 + 31553077 = 31553354
337 + 31553017 = 31553354
463 + 31552891 = 31553354
523 + 31552831 = 31553354
607 + 31552747 = 31553354
661 + 31552693 = 31553354

Showing the first eight; more decompositions exist.
