Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 15446, here are decompositions:

3 + 15443 = 15446
7 + 15439 = 15446
19 + 15427 = 15446
73 + 15373 = 15446
97 + 15349 = 15446
127 + 15319 = 15446
139 + 15307 = 15446
157 + 15289 = 15446

Showing the first eight; more decompositions exist.
