Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712112, here are decompositions:

53 + 8712059 = 8712112
83 + 8712029 = 8712112
179 + 8711933 = 8712112
191 + 8711921 = 8712112
263 + 8711849 = 8712112
443 + 8711669 = 8712112
491 + 8711621 = 8712112
509 + 8711603 = 8712112

Showing the first eight; more decompositions exist.
