Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72802, here are decompositions:

5 + 72797 = 72802
83 + 72719 = 72802
101 + 72701 = 72802
113 + 72689 = 72802
131 + 72671 = 72802
179 + 72623 = 72802
251 + 72551 = 72802
269 + 72533 = 72802

Showing the first eight; more decompositions exist.
