Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187404, here are decompositions:

11 + 187393 = 187404
17 + 187387 = 187404
31 + 187373 = 187404
37 + 187367 = 187404
43 + 187361 = 187404
67 + 187337 = 187404
101 + 187303 = 187404
127 + 187277 = 187404

Showing the first eight; more decompositions exist.
