Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1055242, here are decompositions:

11 + 1055231 = 1055242
53 + 1055189 = 1055242
101 + 1055141 = 1055242
179 + 1055063 = 1055242
311 + 1054931 = 1055242
389 + 1054853 = 1055242
509 + 1054733 = 1055242
521 + 1054721 = 1055242

Showing the first eight; more decompositions exist.
