Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712478, here are decompositions:

107 + 8712371 = 8712478
167 + 8712311 = 8712478
191 + 8712287 = 8712478
197 + 8712281 = 8712478
251 + 8712227 = 8712478
311 + 8712167 = 8712478
419 + 8712059 = 8712478
449 + 8712029 = 8712478

Showing the first eight; more decompositions exist.
