Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1045538, here are decompositions:

31 + 1045507 = 1045538
127 + 1045411 = 1045538
229 + 1045309 = 1045538
409 + 1045129 = 1045538
421 + 1045117 = 1045538
457 + 1045081 = 1045538
541 + 1044997 = 1045538
607 + 1044931 = 1045538

Showing the first eight; more decompositions exist.
