Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712148, here are decompositions:

89 + 8712059 = 8712148
131 + 8712017 = 8712148
197 + 8711951 = 8712148
227 + 8711921 = 8712148
251 + 8711897 = 8712148
281 + 8711867 = 8712148
479 + 8711669 = 8712148
491 + 8711657 = 8712148

Showing the first eight; more decompositions exist.
