Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8748442, here are decompositions:

11 + 8748431 = 8748442
23 + 8748419 = 8748442
29 + 8748413 = 8748442
83 + 8748359 = 8748442
113 + 8748329 = 8748442
179 + 8748263 = 8748442
233 + 8748209 = 8748442
239 + 8748203 = 8748442

Showing the first eight; more decompositions exist.
