Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981470, here are decompositions:

3 + 981467 = 981470
19 + 981451 = 981470
31 + 981439 = 981470
73 + 981397 = 981470
79 + 981391 = 981470
97 + 981373 = 981470
151 + 981319 = 981470
181 + 981289 = 981470

Showing the first eight; more decompositions exist.
