Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1042242, here are decompositions:

31 + 1042211 = 1042242
59 + 1042183 = 1042242
101 + 1042141 = 1042242
109 + 1042133 = 1042242
139 + 1042103 = 1042242
151 + 1042091 = 1042242
199 + 1042043 = 1042242
241 + 1042001 = 1042242

Showing the first eight; more decompositions exist.
