Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659372, here are decompositions:

83 + 8659289 = 8659372
149 + 8659223 = 8659372
191 + 8659181 = 8659372
251 + 8659121 = 8659372
311 + 8659061 = 8659372
353 + 8659019 = 8659372
383 + 8658989 = 8659372
389 + 8658983 = 8659372

Showing the first eight; more decompositions exist.
