Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8612542, here are decompositions:

11 + 8612531 = 8612542
131 + 8612411 = 8612542
443 + 8612099 = 8612542
503 + 8612039 = 8612542
509 + 8612033 = 8612542
683 + 8611859 = 8612542
821 + 8611721 = 8612542
839 + 8611703 = 8612542

Showing the first eight; more decompositions exist.
