Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8702904, here are decompositions:

61 + 8702843 = 8702904
71 + 8702833 = 8702904
83 + 8702821 = 8702904
101 + 8702803 = 8702904
127 + 8702777 = 8702904
151 + 8702753 = 8702904
157 + 8702747 = 8702904
173 + 8702731 = 8702904

Showing the first eight; more decompositions exist.
