Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987632, here are decompositions:

73 + 987559 = 987632
109 + 987523 = 987632
199 + 987433 = 987632
241 + 987391 = 987632
271 + 987361 = 987632
421 + 987211 = 987632
433 + 987199 = 987632
439 + 987193 = 987632

Showing the first eight; more decompositions exist.
