Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87844, here are decompositions:

11 + 87833 = 87844
41 + 87803 = 87844
47 + 87797 = 87844
101 + 87743 = 87844
173 + 87671 = 87844
257 + 87587 = 87844
353 + 87491 = 87844
401 + 87443 = 87844

Showing the first eight; more decompositions exist.
