Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744842, here are decompositions:

5 + 8744837 = 8744842
11 + 8744831 = 8744842
23 + 8744819 = 8744842
131 + 8744711 = 8744842
179 + 8744663 = 8744842
383 + 8744459 = 8744842
419 + 8744423 = 8744842
599 + 8744243 = 8744842

Showing the first eight; more decompositions exist.
