Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8664144, here are decompositions:

37 + 8664107 = 8664144
101 + 8664043 = 8664144
107 + 8664037 = 8664144
157 + 8663987 = 8664144
283 + 8663861 = 8664144
317 + 8663827 = 8664144
337 + 8663807 = 8664144
347 + 8663797 = 8664144

Showing the first eight; more decompositions exist.
