Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 987572, here are decompositions:

13 + 987559 = 987572
31 + 987541 = 987572
109 + 987463 = 987572
139 + 987433 = 987572
181 + 987391 = 987572
211 + 987361 = 987572
373 + 987199 = 987572
379 + 987193 = 987572

Showing the first eight; more decompositions exist.
