Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743890, here are decompositions:

7 + 8743883 = 8743890
11 + 8743879 = 8743890
37 + 8743853 = 8743890
47 + 8743843 = 8743890
53 + 8743837 = 8743890
73 + 8743817 = 8743890
83 + 8743807 = 8743890
137 + 8743753 = 8743890

Showing the first eight; more decompositions exist.
