Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707982, here are decompositions:

13 + 8707969 = 8707982
43 + 8707939 = 8707982
79 + 8707903 = 8707982
103 + 8707879 = 8707982
109 + 8707873 = 8707982
139 + 8707843 = 8707982
229 + 8707753 = 8707982
271 + 8707711 = 8707982

Showing the first eight; more decompositions exist.
