Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 18862, here are decompositions:

3 + 18859 = 18862
23 + 18839 = 18862
59 + 18803 = 18862
89 + 18773 = 18862
113 + 18749 = 18862
131 + 18731 = 18862
149 + 18713 = 18862
191 + 18671 = 18862

Showing the first eight; more decompositions exist.
