Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981254, here are decompositions:

13 + 981241 = 981254
67 + 981187 = 981254
103 + 981151 = 981254
163 + 981091 = 981254
181 + 981073 = 981254
193 + 981061 = 981254
367 + 980887 = 981254
523 + 980731 = 981254

Showing the first eight; more decompositions exist.
