Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127572, here are decompositions:

23 + 127549 = 127572
31 + 127541 = 127572
43 + 127529 = 127572
79 + 127493 = 127572
149 + 127423 = 127572
173 + 127399 = 127572
199 + 127373 = 127572
229 + 127343 = 127572

Showing the first eight; more decompositions exist.
