Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187622, here are decompositions:

109 + 187513 = 187622
151 + 187471 = 187622
181 + 187441 = 187622
199 + 187423 = 187622
229 + 187393 = 187622
283 + 187339 = 187622
349 + 187273 = 187622
433 + 187189 = 187622

Showing the first eight; more decompositions exist.
