Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981524, here are decompositions:

7 + 981517 = 981524
31 + 981493 = 981524
43 + 981481 = 981524
73 + 981451 = 981524
127 + 981397 = 981524
151 + 981373 = 981524
223 + 981301 = 981524
241 + 981283 = 981524

Showing the first eight; more decompositions exist.
