Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72862, here are decompositions:

3 + 72859 = 72862
173 + 72689 = 72862
191 + 72671 = 72862
239 + 72623 = 72862
311 + 72551 = 72862
359 + 72503 = 72862
401 + 72461 = 72862
431 + 72431 = 72862

Showing the first eight; more decompositions exist.
