Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87402, here are decompositions:

19 + 87383 = 87402
43 + 87359 = 87402
79 + 87323 = 87402
89 + 87313 = 87402
103 + 87299 = 87402
109 + 87293 = 87402
149 + 87253 = 87402
151 + 87251 = 87402

Showing the first eight; more decompositions exist.
