Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8690418, here are decompositions:

5 + 8690413 = 8690418
7 + 8690411 = 8690418
19 + 8690399 = 8690418
31 + 8690387 = 8690418
41 + 8690377 = 8690418
47 + 8690371 = 8690418
59 + 8690359 = 8690418
67 + 8690351 = 8690418

Showing the first eight; more decompositions exist.
