Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981232, here are decompositions:

11 + 981221 = 981232
23 + 981209 = 981232
59 + 981173 = 981232
233 + 980999 = 981232
269 + 980963 = 981232
311 + 980921 = 981232
401 + 980831 = 981232
431 + 980801 = 981232

Showing the first eight; more decompositions exist.
