Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987492, here are decompositions:

19 + 987473 = 987492
29 + 987463 = 987492
59 + 987433 = 987492
101 + 987391 = 987492
109 + 987383 = 987492
131 + 987361 = 987492
139 + 987353 = 987492
179 + 987313 = 987492

Showing the first eight; more decompositions exist.
