Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187554, here are decompositions:

7 + 187547 = 187554
23 + 187531 = 187554
41 + 187513 = 187554
47 + 187507 = 187554
83 + 187471 = 187554
113 + 187441 = 187554
131 + 187423 = 187554
137 + 187417 = 187554

Showing the first eight; more decompositions exist.
