Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127422, here are decompositions:

19 + 127403 = 127422
23 + 127399 = 127422
59 + 127363 = 127422
79 + 127343 = 127422
101 + 127321 = 127422
131 + 127291 = 127422
151 + 127271 = 127422
173 + 127249 = 127422

Showing the first eight; more decompositions exist.
