Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103750, here are decompositions:

47 + 103703 = 103750
107 + 103643 = 103750
131 + 103619 = 103750
137 + 103613 = 103750
167 + 103583 = 103750
173 + 103577 = 103750
197 + 103553 = 103750
239 + 103511 = 103750

Showing the first eight; more decompositions exist.
