Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187140, here are decompositions:

7 + 187133 = 187140
11 + 187129 = 187140
13 + 187127 = 187140
17 + 187123 = 187140
29 + 187111 = 187140
59 + 187081 = 187140
67 + 187073 = 187140
71 + 187069 = 187140

Showing the first eight; more decompositions exist.
