Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87176, here are decompositions:

43 + 87133 = 87176
73 + 87103 = 87176
127 + 87049 = 87176
139 + 87037 = 87176
163 + 87013 = 87176
307 + 86869 = 87176
409 + 86767 = 87176
433 + 86743 = 87176

Showing the first eight; more decompositions exist.
