Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187758, here are decompositions:

7 + 187751 = 187758
37 + 187721 = 187758
47 + 187711 = 187758
59 + 187699 = 187758
71 + 187687 = 187758
89 + 187669 = 187758
97 + 187661 = 187758
107 + 187651 = 187758

Showing the first eight; more decompositions exist.
