Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615370, here are decompositions:

37 + 8615333 = 8615370
47 + 8615323 = 8615370
83 + 8615287 = 8615370
97 + 8615273 = 8615370
103 + 8615267 = 8615370
109 + 8615261 = 8615370
139 + 8615231 = 8615370
151 + 8615219 = 8615370

Showing the first eight; more decompositions exist.
