Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8615372, here are decompositions:

211 + 8615161 = 8615372
223 + 8615149 = 8615372
421 + 8614951 = 8615372
433 + 8614939 = 8615372
499 + 8614873 = 8615372
523 + 8614849 = 8615372
541 + 8614831 = 8615372
613 + 8614759 = 8615372

Showing the first eight; more decompositions exist.
