Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 171140, here are decompositions:

37 + 171103 = 171140
61 + 171079 = 171140
97 + 171043 = 171140
241 + 170899 = 171140
283 + 170857 = 171140
313 + 170827 = 171140
331 + 170809 = 171140
367 + 170773 = 171140

Showing the first eight; more decompositions exist.
