Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637424, here are decompositions:

83 + 8637341 = 8637424
101 + 8637323 = 8637424
113 + 8637311 = 8637424
167 + 8637257 = 8637424
197 + 8637227 = 8637424
293 + 8637131 = 8637424
317 + 8637107 = 8637424
503 + 8636921 = 8637424

Showing the first eight; more decompositions exist.
