Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707938, here are decompositions:

59 + 8707879 = 8707938
61 + 8707877 = 8707938
97 + 8707841 = 8707938
101 + 8707837 = 8707938
157 + 8707781 = 8707938
191 + 8707747 = 8707938
227 + 8707711 = 8707938
241 + 8707697 = 8707938

Showing the first eight; more decompositions exist.
