Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553338, here are decompositions:

17 + 31553321 = 31553338
59 + 31553279 = 31553338
137 + 31553201 = 31553338
269 + 31553069 = 31553338
317 + 31553021 = 31553338
419 + 31552919 = 31553338
431 + 31552907 = 31553338
491 + 31552847 = 31553338

Showing the first eight; more decompositions exist.
