Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027542, here are decompositions:

23 + 1027519 = 1027542
53 + 1027489 = 1027542
59 + 1027483 = 1027542
71 + 1027471 = 1027542
83 + 1027459 = 1027542
151 + 1027391 = 1027542
211 + 1027331 = 1027542
223 + 1027319 = 1027542

Showing the first eight; more decompositions exist.
