Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187750, here are decompositions:

29 + 187721 = 187750
89 + 187661 = 187750
113 + 187637 = 187750
191 + 187559 = 187750
281 + 187469 = 187750
317 + 187433 = 187750
383 + 187367 = 187750
389 + 187361 = 187750

Showing the first eight; more decompositions exist.
