Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87470, here are decompositions:

37 + 87433 = 87470
43 + 87427 = 87470
67 + 87403 = 87470
157 + 87313 = 87470
193 + 87277 = 87470
283 + 87187 = 87470
337 + 87133 = 87470
349 + 87121 = 87470

Showing the first eight; more decompositions exist.
