Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981032, here are decompositions:

139 + 980893 = 981032
181 + 980851 = 981032
229 + 980803 = 981032
313 + 980719 = 981032
433 + 980599 = 981032
439 + 980593 = 981032
541 + 980491 = 981032
601 + 980431 = 981032

Showing the first eight; more decompositions exist.
