Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981674, here are decompositions:

37 + 981637 = 981674
73 + 981601 = 981674
97 + 981577 = 981674
151 + 981523 = 981674
157 + 981517 = 981674
181 + 981493 = 981674
193 + 981481 = 981674
223 + 981451 = 981674

Showing the first eight; more decompositions exist.
