Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712424, here are decompositions:

3 + 8712421 = 8712424
53 + 8712371 = 8712424
101 + 8712323 = 8712424
113 + 8712311 = 8712424
131 + 8712293 = 8712424
137 + 8712287 = 8712424
167 + 8712257 = 8712424
191 + 8712233 = 8712424

Showing the first eight; more decompositions exist.
