Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644156, here are decompositions:

107 + 8644049 = 8644156
137 + 8644019 = 8644156
197 + 8643959 = 8644156
233 + 8643923 = 8644156
263 + 8643893 = 8644156
317 + 8643839 = 8644156
359 + 8643797 = 8644156
449 + 8643707 = 8644156

Showing the first eight; more decompositions exist.
