Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637436, here are decompositions:

113 + 8637323 = 8637436
173 + 8637263 = 8637436
179 + 8637257 = 8637436
233 + 8637203 = 8637436
257 + 8637179 = 8637436
317 + 8637119 = 8637436
383 + 8637053 = 8637436
419 + 8637017 = 8637436

Showing the first eight; more decompositions exist.
