Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702940, here are decompositions:

61 + 8702879 = 8702940
97 + 8702843 = 8702940
101 + 8702839 = 8702940
107 + 8702833 = 8702940
137 + 8702803 = 8702940
163 + 8702777 = 8702940
193 + 8702747 = 8702940
241 + 8702699 = 8702940

Showing the first eight; more decompositions exist.
