Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187144, here are decompositions:

3 + 187141 = 187144
5 + 187139 = 187144
11 + 187133 = 187144
17 + 187127 = 187144
53 + 187091 = 187144
71 + 187073 = 187144
101 + 187043 = 187144
197 + 186947 = 187144

Showing the first eight; more decompositions exist.
