Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1038242, here are decompositions:

31 + 1038211 = 1038242
43 + 1038199 = 1038242
199 + 1038043 = 1038242
223 + 1038019 = 1038242
241 + 1038001 = 1038242
313 + 1037929 = 1038242
349 + 1037893 = 1038242
631 + 1037611 = 1038242

Showing the first eight; more decompositions exist.
