Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 86554, here are decompositions:

23 + 86531 = 86554
53 + 86501 = 86554
101 + 86453 = 86554
113 + 86441 = 86554
131 + 86423 = 86554
173 + 86381 = 86554
197 + 86357 = 86554
257 + 86297 = 86554

Showing the first eight; more decompositions exist.
