Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712158, here are decompositions:

67 + 8712091 = 8712158
139 + 8712019 = 8712158
271 + 8711887 = 8712158
307 + 8711851 = 8712158
337 + 8711821 = 8712158
409 + 8711749 = 8712158
421 + 8711737 = 8712158
439 + 8711719 = 8712158

Showing the first eight; more decompositions exist.
