Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981182, here are decompositions:

31 + 981151 = 981182
43 + 981139 = 981182
109 + 981073 = 981182
271 + 980911 = 981182
283 + 980899 = 981182
331 + 980851 = 981182
379 + 980803 = 981182
409 + 980773 = 981182

Showing the first eight; more decompositions exist.
