Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87506, here are decompositions:

73 + 87433 = 87506
79 + 87427 = 87506
103 + 87403 = 87506
193 + 87313 = 87506
229 + 87277 = 87506
283 + 87223 = 87506
373 + 87133 = 87506
457 + 87049 = 87506

Showing the first eight; more decompositions exist.
