Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187394, here are decompositions:

7 + 187387 = 187394
157 + 187237 = 187394
223 + 187171 = 187394
271 + 187123 = 187394
283 + 187111 = 187394
313 + 187081 = 187394
367 + 187027 = 187394
523 + 186871 = 187394

Showing the first eight; more decompositions exist.
