Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187764, here are decompositions:

13 + 187751 = 187764
43 + 187721 = 187764
53 + 187711 = 187764
103 + 187661 = 187764
113 + 187651 = 187764
127 + 187637 = 187764
131 + 187633 = 187764
167 + 187597 = 187764

Showing the first eight; more decompositions exist.
