Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8623378, here are decompositions:

59 + 8623319 = 8623378
131 + 8623247 = 8623378
311 + 8623067 = 8623378
317 + 8623061 = 8623378
347 + 8623031 = 8623378
359 + 8623019 = 8623378
419 + 8622959 = 8623378
521 + 8622857 = 8623378

Showing the first eight; more decompositions exist.
