Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712040, here are decompositions:

11 + 8712029 = 8712040
23 + 8712017 = 8712040
53 + 8711987 = 8712040
89 + 8711951 = 8712040
107 + 8711933 = 8712040
173 + 8711867 = 8712040
191 + 8711849 = 8712040
257 + 8711783 = 8712040

Showing the first eight; more decompositions exist.
