Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981662, here are decompositions:

61 + 981601 = 981662
139 + 981523 = 981662
181 + 981481 = 981662
211 + 981451 = 981662
223 + 981439 = 981662
271 + 981391 = 981662
373 + 981289 = 981662
379 + 981283 = 981662

Showing the first eight; more decompositions exist.
