Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719420, here are decompositions:

29 + 8719391 = 8719420
41 + 8719379 = 8719420
53 + 8719367 = 8719420
71 + 8719349 = 8719420
113 + 8719307 = 8719420
131 + 8719289 = 8719420
167 + 8719253 = 8719420
197 + 8719223 = 8719420

Showing the first eight; more decompositions exist.
