Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187436, here are decompositions:

3 + 187433 = 187436
13 + 187423 = 187436
19 + 187417 = 187436
43 + 187393 = 187436
97 + 187339 = 187436
163 + 187273 = 187436
199 + 187237 = 187436
307 + 187129 = 187436

Showing the first eight; more decompositions exist.
