Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615042, here are decompositions:

103 + 8614939 = 8615042
193 + 8614849 = 8615042
211 + 8614831 = 8615042
283 + 8614759 = 8615042
313 + 8614729 = 8615042
349 + 8614693 = 8615042
433 + 8614609 = 8615042
463 + 8614579 = 8615042

Showing the first eight; more decompositions exist.
