Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981326, here are decompositions:

7 + 981319 = 981326
37 + 981289 = 981326
43 + 981283 = 981326
127 + 981199 = 981326
139 + 981187 = 981326
193 + 981133 = 981326
277 + 981049 = 981326
433 + 980893 = 981326

Showing the first eight; more decompositions exist.
