Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987902, here are decompositions:

109 + 987793 = 987902
163 + 987739 = 987902
271 + 987631 = 987902
379 + 987523 = 987902
439 + 987463 = 987902
541 + 987361 = 987902
691 + 987211 = 987902
709 + 987193 = 987902

Showing the first eight; more decompositions exist.
