Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600378, here are decompositions:

19 + 8600359 = 8600378
37 + 8600341 = 8600378
139 + 8600239 = 8600378
277 + 8600101 = 8600378
307 + 8600071 = 8600378
331 + 8600047 = 8600378
337 + 8600041 = 8600378
349 + 8600029 = 8600378

Showing the first eight; more decompositions exist.
