Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15698, here are decompositions:

19 + 15679 = 15698
31 + 15667 = 15698
37 + 15661 = 15698
79 + 15619 = 15698
97 + 15601 = 15698
139 + 15559 = 15698
157 + 15541 = 15698
271 + 15427 = 15698

Showing the first eight; more decompositions exist.
