Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87802, here are decompositions:

5 + 87797 = 87802
59 + 87743 = 87802
83 + 87719 = 87802
101 + 87701 = 87802
131 + 87671 = 87802
173 + 87629 = 87802
179 + 87623 = 87802
263 + 87539 = 87802

Showing the first eight; more decompositions exist.
