Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31590554, here are decompositions:

3 + 31590551 = 31590554
67 + 31590487 = 31590554
103 + 31590451 = 31590554
157 + 31590397 = 31590554
211 + 31590343 = 31590554
241 + 31590313 = 31590554
277 + 31590277 = 31590554
313 + 31590241 = 31590554

Showing the first eight; more decompositions exist.
