Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87862, here are decompositions:

29 + 87833 = 87862
59 + 87803 = 87862
179 + 87683 = 87862
191 + 87671 = 87862
233 + 87629 = 87862
239 + 87623 = 87862
353 + 87509 = 87862
389 + 87473 = 87862

Showing the first eight; more decompositions exist.
