Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492554, here are decompositions:

13 + 31492541 = 31492554
17 + 31492537 = 31492554
61 + 31492493 = 31492554
83 + 31492471 = 31492554
101 + 31492453 = 31492554
131 + 31492423 = 31492554
151 + 31492403 = 31492554
277 + 31492277 = 31492554

Showing the first eight; more decompositions exist.
