Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637406, here are decompositions:

83 + 8637323 = 8637406
149 + 8637257 = 8637406
179 + 8637227 = 8637406
227 + 8637179 = 8637406
347 + 8637059 = 8637406
353 + 8637053 = 8637406
389 + 8637017 = 8637406
419 + 8636987 = 8637406

Showing the first eight; more decompositions exist.
