Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637394, here are decompositions:

53 + 8637341 = 8637394
71 + 8637323 = 8637394
83 + 8637311 = 8637394
131 + 8637263 = 8637394
137 + 8637257 = 8637394
167 + 8637227 = 8637394
191 + 8637203 = 8637394
263 + 8637131 = 8637394

Showing the first eight; more decompositions exist.
