Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187018, here are decompositions:

59 + 186959 = 187018
71 + 186947 = 187018
101 + 186917 = 187018
149 + 186869 = 187018
257 + 186761 = 187018
311 + 186707 = 187018
317 + 186701 = 187018
347 + 186671 = 187018

Showing the first eight; more decompositions exist.
