Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739972, here are decompositions:

5 + 8739967 = 8739972
11 + 8739961 = 8739972
19 + 8739953 = 8739972
53 + 8739919 = 8739972
61 + 8739911 = 8739972
71 + 8739901 = 8739972
89 + 8739883 = 8739972
103 + 8739869 = 8739972

Showing the first eight; more decompositions exist.
