Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981554, here are decompositions:

31 + 981523 = 981554
37 + 981517 = 981554
61 + 981493 = 981554
73 + 981481 = 981554
103 + 981451 = 981554
157 + 981397 = 981554
163 + 981391 = 981554
181 + 981373 = 981554

Showing the first eight; more decompositions exist.
