Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187626, here are decompositions:

29 + 187597 = 187626
53 + 187573 = 187626
67 + 187559 = 187626
79 + 187547 = 187626
113 + 187513 = 187626
149 + 187477 = 187626
157 + 187469 = 187626
163 + 187463 = 187626

Showing the first eight; more decompositions exist.
