Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187982, here are decompositions:

19 + 187963 = 187982
31 + 187951 = 187982
61 + 187921 = 187982
73 + 187909 = 187982
139 + 187843 = 187982
271 + 187711 = 187982
283 + 187699 = 187982
313 + 187669 = 187982

Showing the first eight; more decompositions exist.
