Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553384, here are decompositions:

151 + 31553233 = 31553384
223 + 31553161 = 31553384
307 + 31553077 = 31553384
367 + 31553017 = 31553384
691 + 31552693 = 31553384
991 + 31552393 = 31553384
997 + 31552387 = 31553384
1033 + 31552351 = 31553384

Showing the first eight; more decompositions exist.
