Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553396, here are decompositions:

13 + 31553383 = 31553396
37 + 31553359 = 31553396
163 + 31553233 = 31553396
307 + 31553089 = 31553396
379 + 31553017 = 31553396
397 + 31552999 = 31553396
757 + 31552639 = 31553396
859 + 31552537 = 31553396

Showing the first eight; more decompositions exist.
