Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31553494, here are decompositions:

41 + 31553453 = 31553494
107 + 31553387 = 31553494
173 + 31553321 = 31553494
233 + 31553261 = 31553494
281 + 31553213 = 31553494
293 + 31553201 = 31553494
311 + 31553183 = 31553494
317 + 31553177 = 31553494

Showing the first eight; more decompositions exist.
