Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187662, here are decompositions:

11 + 187651 = 187662
23 + 187639 = 187662
29 + 187633 = 187662
31 + 187631 = 187662
89 + 187573 = 187662
103 + 187559 = 187662
131 + 187531 = 187662
149 + 187513 = 187662

Showing the first eight; more decompositions exist.
