Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187744, here are decompositions:

23 + 187721 = 187744
83 + 187661 = 187744
107 + 187637 = 187744
113 + 187631 = 187744
197 + 187547 = 187744
281 + 187463 = 187744
311 + 187433 = 187744
383 + 187361 = 187744

Showing the first eight; more decompositions exist.
