Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8650144, here are decompositions:

3 + 8650141 = 8650144
23 + 8650121 = 8650144
233 + 8649911 = 8650144
257 + 8649887 = 8650144
263 + 8649881 = 8650144
353 + 8649791 = 8650144
383 + 8649761 = 8650144
467 + 8649677 = 8650144

Showing the first eight; more decompositions exist.
