Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690644, here are decompositions:

5 + 8690639 = 8690644
41 + 8690603 = 8690644
113 + 8690531 = 8690644
167 + 8690477 = 8690644
191 + 8690453 = 8690644
233 + 8690411 = 8690644
257 + 8690387 = 8690644
293 + 8690351 = 8690644

Showing the first eight; more decompositions exist.
