Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187162, here are decompositions:

23 + 187139 = 187162
29 + 187133 = 187162
71 + 187091 = 187162
89 + 187073 = 187162
113 + 187049 = 187162
293 + 186869 = 187162
389 + 186773 = 187162
401 + 186761 = 187162

Showing the first eight; more decompositions exist.
