Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187244, here are decompositions:

7 + 187237 = 187244
67 + 187177 = 187244
73 + 187171 = 187244
103 + 187141 = 187244
163 + 187081 = 187244
241 + 187003 = 187244
367 + 186877 = 187244
373 + 186871 = 187244

Showing the first eight; more decompositions exist.
