Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637448, here are decompositions:

107 + 8637341 = 8637448
137 + 8637311 = 8637448
191 + 8637257 = 8637448
269 + 8637179 = 8637448
317 + 8637131 = 8637448
389 + 8637059 = 8637448
431 + 8637017 = 8637448
461 + 8636987 = 8637448

Showing the first eight; more decompositions exist.
