Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981224, here are decompositions:

3 + 981221 = 981224
37 + 981187 = 981224
73 + 981151 = 981224
151 + 981073 = 981224
157 + 981067 = 981224
163 + 981061 = 981224
313 + 980911 = 981224
331 + 980893 = 981224

Showing the first eight; more decompositions exist.
