Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 572158, here are decompositions:

71 + 572087 = 572158
89 + 572069 = 572158
107 + 572051 = 572158
131 + 572027 = 572158
281 + 571877 = 572158
311 + 571847 = 572158
317 + 571841 = 572158
347 + 571811 = 572158

Showing the first eight; more decompositions exist.
