Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981262, here are decompositions:

41 + 981221 = 981262
53 + 981209 = 981262
89 + 981173 = 981262
239 + 981023 = 981262
251 + 981011 = 981262
263 + 980999 = 981262
353 + 980909 = 981262
431 + 980831 = 981262

Showing the first eight; more decompositions exist.
