Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615432, here are decompositions:

43 + 8615389 = 8615432
109 + 8615323 = 8615432
271 + 8615161 = 8615432
283 + 8615149 = 8615432
349 + 8615083 = 8615432
601 + 8614831 = 8615432
643 + 8614789 = 8615432
673 + 8614759 = 8615432

Showing the first eight; more decompositions exist.
