Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187380, here are decompositions:

7 + 187373 = 187380
13 + 187367 = 187380
19 + 187361 = 187380
31 + 187349 = 187380
41 + 187339 = 187380
43 + 187337 = 187380
103 + 187277 = 187380
107 + 187273 = 187380

Showing the first eight; more decompositions exist.
