Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553634, here are decompositions:

17 + 31553617 = 31553634
107 + 31553527 = 31553634
131 + 31553503 = 31553634
181 + 31553453 = 31553634
251 + 31553383 = 31553634
283 + 31553351 = 31553634
313 + 31553321 = 31553634
373 + 31553261 = 31553634

Showing the first eight; more decompositions exist.
