Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700972, here are decompositions:

19 + 8700953 = 8700972
31 + 8700941 = 8700972
41 + 8700931 = 8700972
61 + 8700911 = 8700972
79 + 8700893 = 8700972
101 + 8700871 = 8700972
103 + 8700869 = 8700972
139 + 8700833 = 8700972

Showing the first eight; more decompositions exist.
