Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712422, here are decompositions:

73 + 8712349 = 8712422
163 + 8712259 = 8712422
193 + 8712229 = 8712422
241 + 8712181 = 8712422
331 + 8712091 = 8712422
571 + 8711851 = 8712422
601 + 8711821 = 8712422
673 + 8711749 = 8712422

Showing the first eight; more decompositions exist.
