Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187412, here are decompositions:

3 + 187409 = 187412
19 + 187393 = 187412
73 + 187339 = 187412
109 + 187303 = 187412
139 + 187273 = 187412
193 + 187219 = 187412
223 + 187189 = 187412
241 + 187171 = 187412

Showing the first eight; more decompositions exist.
