Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709378, here are decompositions:

5 + 8709373 = 8709378
17 + 8709361 = 8709378
61 + 8709317 = 8709378
79 + 8709299 = 8709378
89 + 8709289 = 8709378
107 + 8709271 = 8709378
149 + 8709229 = 8709378
157 + 8709221 = 8709378

Showing the first eight; more decompositions exist.
