Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637442, here are decompositions:

101 + 8637341 = 8637442
131 + 8637311 = 8637442
179 + 8637263 = 8637442
239 + 8637203 = 8637442
263 + 8637179 = 8637442
311 + 8637131 = 8637442
383 + 8637059 = 8637442
389 + 8637053 = 8637442

Showing the first eight; more decompositions exist.
