Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700444, here are decompositions:

13 + 8700431 = 8700444
23 + 8700421 = 8700444
37 + 8700407 = 8700444
43 + 8700401 = 8700444
61 + 8700383 = 8700444
83 + 8700361 = 8700444
157 + 8700287 = 8700444
163 + 8700281 = 8700444

Showing the first eight; more decompositions exist.
