Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187074, here are decompositions:

5 + 187069 = 187074
7 + 187067 = 187074
31 + 187043 = 187074
47 + 187027 = 187074
71 + 187003 = 187074
127 + 186947 = 187074
157 + 186917 = 187074
191 + 186883 = 187074

Showing the first eight; more decompositions exist.
