Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87292, here are decompositions:

11 + 87281 = 87292
41 + 87251 = 87292
71 + 87221 = 87292
113 + 87179 = 87292
173 + 87119 = 87292
251 + 87041 = 87292
281 + 87011 = 87292
311 + 86981 = 87292

Showing the first eight; more decompositions exist.
