Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15758, here are decompositions:

19 + 15739 = 15758
31 + 15727 = 15758
79 + 15679 = 15758
97 + 15661 = 15758
109 + 15649 = 15758
139 + 15619 = 15758
151 + 15607 = 15758
157 + 15601 = 15758

Showing the first eight; more decompositions exist.
