Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8712420, here are decompositions:

23 + 8712397 = 8712420
47 + 8712373 = 8712420
53 + 8712367 = 8712420
71 + 8712349 = 8712420
83 + 8712337 = 8712420
97 + 8712323 = 8712420
109 + 8712311 = 8712420
113 + 8712307 = 8712420

Showing the first eight; more decompositions exist.
