Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615444, here are decompositions:

67 + 8615377 = 8615444
157 + 8615287 = 8615444
283 + 8615161 = 8615444
307 + 8615137 = 8615444
457 + 8614987 = 8615444
571 + 8614873 = 8615444
577 + 8614867 = 8615444
613 + 8614831 = 8615444

Showing the first eight; more decompositions exist.
