Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047242, here are decompositions:

3 + 1047239 = 1047242
13 + 1047229 = 1047242
43 + 1047199 = 1047242
103 + 1047139 = 1047242
109 + 1047133 = 1047242
181 + 1047061 = 1047242
199 + 1047043 = 1047242
211 + 1047031 = 1047242

Showing the first eight; more decompositions exist.
