Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1023142, here are decompositions:

41 + 1023101 = 1023142
59 + 1023083 = 1023142
101 + 1023041 = 1023142
179 + 1022963 = 1023142
251 + 1022891 = 1023142
293 + 1022849 = 1023142
503 + 1022639 = 1023142
509 + 1022633 = 1023142

Showing the first eight; more decompositions exist.
