Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102748, here are decompositions:

47 + 102701 = 102748
71 + 102677 = 102748
101 + 102647 = 102748
137 + 102611 = 102748
197 + 102551 = 102748
251 + 102497 = 102748
311 + 102437 = 102748
389 + 102359 = 102748

Showing the first eight; more decompositions exist.
