Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690378, here are decompositions:

7 + 8690371 = 8690378
19 + 8690359 = 8690378
61 + 8690317 = 8690378
157 + 8690221 = 8690378
337 + 8690041 = 8690378
397 + 8689981 = 8690378
409 + 8689969 = 8690378
421 + 8689957 = 8690378

Showing the first eight; more decompositions exist.
