Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981764, here are decompositions:

61 + 981703 = 981764
67 + 981697 = 981764
73 + 981691 = 981764
127 + 981637 = 981764
163 + 981601 = 981764
241 + 981523 = 981764
271 + 981493 = 981764
283 + 981481 = 981764

Showing the first eight; more decompositions exist.
