Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027242, here are decompositions:

19 + 1027223 = 1027242
31 + 1027211 = 1027242
43 + 1027199 = 1027242
53 + 1027189 = 1027242
61 + 1027181 = 1027242
79 + 1027163 = 1027242
89 + 1027153 = 1027242
103 + 1027139 = 1027242

Showing the first eight; more decompositions exist.
