Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 188008, here are decompositions:

101 + 187907 = 188008
131 + 187877 = 188008
137 + 187871 = 188008
257 + 187751 = 188008
347 + 187661 = 188008
449 + 187559 = 188008
461 + 187547 = 188008
599 + 187409 = 188008

Showing the first eight; more decompositions exist.
