Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187174, here are decompositions:

3 + 187171 = 187174
11 + 187163 = 187174
41 + 187133 = 187174
47 + 187127 = 187174
83 + 187091 = 187174
101 + 187073 = 187174
107 + 187067 = 187174
131 + 187043 = 187174

Showing the first eight; more decompositions exist.
