Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187148, here are decompositions:

7 + 187141 = 187148
19 + 187129 = 187148
37 + 187111 = 187148
67 + 187081 = 187148
79 + 187069 = 187148
139 + 187009 = 187148
271 + 186877 = 187148
277 + 186871 = 187148

Showing the first eight; more decompositions exist.
