Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8744850, here are decompositions:

7 + 8744843 = 8744850
13 + 8744837 = 8744850
17 + 8744833 = 8744850
19 + 8744831 = 8744850
31 + 8744819 = 8744850
113 + 8744737 = 8744850
139 + 8744711 = 8744850
167 + 8744683 = 8744850

Showing the first eight; more decompositions exist.
