Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553246, here are decompositions:

13 + 31553233 = 31553246
157 + 31553089 = 31553246
229 + 31553017 = 31553246
367 + 31552879 = 31553246
499 + 31552747 = 31553246
607 + 31552639 = 31553246
643 + 31552603 = 31553246
709 + 31552537 = 31553246

Showing the first eight; more decompositions exist.
