Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 981492, here are decompositions:

11 + 981481 = 981492
19 + 981473 = 981492
41 + 981451 = 981492
53 + 981439 = 981492
73 + 981419 = 981492
101 + 981391 = 981492
173 + 981319 = 981492
181 + 981311 = 981492

Showing the first eight; more decompositions exist.
