Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1016288, here are decompositions:

61 + 1016227 = 1016288
67 + 1016221 = 1016288
151 + 1016137 = 1016288
199 + 1016089 = 1016288
277 + 1016011 = 1016288
307 + 1015981 = 1016288
397 + 1015891 = 1016288
541 + 1015747 = 1016288

Showing the first eight; more decompositions exist.
