Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987542, here are decompositions:

19 + 987523 = 987542
79 + 987463 = 987542
109 + 987433 = 987542
151 + 987391 = 987542
181 + 987361 = 987542
229 + 987313 = 987542
331 + 987211 = 987542
349 + 987193 = 987542

Showing the first eight; more decompositions exist.
