Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 87944, here are decompositions:

13 + 87931 = 87944
67 + 87877 = 87944
151 + 87793 = 87944
193 + 87751 = 87944
223 + 87721 = 87944
313 + 87631 = 87944
331 + 87613 = 87944
397 + 87547 = 87944

Showing the first eight; more decompositions exist.
