Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8701378, here are decompositions:

11 + 8701367 = 8701378
29 + 8701349 = 8701378
89 + 8701289 = 8701378
107 + 8701271 = 8701378
167 + 8701211 = 8701378
311 + 8701067 = 8701378
431 + 8700947 = 8701378
467 + 8700911 = 8701378

Showing the first eight; more decompositions exist.
