Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1054142, here are decompositions:

109 + 1054033 = 1054142
139 + 1054003 = 1054142
151 + 1053991 = 1054142
373 + 1053769 = 1054142
571 + 1053571 = 1054142
613 + 1053529 = 1054142
631 + 1053511 = 1054142
823 + 1053319 = 1054142

Showing the first eight; more decompositions exist.
