Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547554, here are decompositions:

23 + 31547531 = 31547554
47 + 31547507 = 31547554
83 + 31547471 = 31547554
113 + 31547441 = 31547554
197 + 31547357 = 31547554
251 + 31547303 = 31547554
257 + 31547297 = 31547554
293 + 31547261 = 31547554

Showing the first eight; more decompositions exist.
