Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187862, here are decompositions:

19 + 187843 = 187862
151 + 187711 = 187862
163 + 187699 = 187862
193 + 187669 = 187862
211 + 187651 = 187862
223 + 187639 = 187862
229 + 187633 = 187862
331 + 187531 = 187862

Showing the first eight; more decompositions exist.
