Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702040, here are decompositions:

31 + 8702009 = 8702040
41 + 8701999 = 8702040
43 + 8701997 = 8702040
79 + 8701961 = 8702040
89 + 8701951 = 8702040
107 + 8701933 = 8702040
157 + 8701883 = 8702040
163 + 8701877 = 8702040

Showing the first eight; more decompositions exist.
