Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15992, here are decompositions:

19 + 15973 = 15992
73 + 15919 = 15992
79 + 15913 = 15992
103 + 15889 = 15992
313 + 15679 = 15992
331 + 15661 = 15992
349 + 15643 = 15992
373 + 15619 = 15992

Showing the first eight; more decompositions exist.
