Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87342, here are decompositions:

5 + 87337 = 87342
19 + 87323 = 87342
29 + 87313 = 87342
43 + 87299 = 87342
61 + 87281 = 87342
89 + 87253 = 87342
131 + 87211 = 87342
163 + 87179 = 87342

Showing the first eight; more decompositions exist.
