Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127470, here are decompositions:

17 + 127453 = 127470
23 + 127447 = 127470
47 + 127423 = 127470
67 + 127403 = 127470
71 + 127399 = 127470
97 + 127373 = 127470
107 + 127363 = 127470
127 + 127343 = 127470

Showing the first eight; more decompositions exist.
