Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172070, here are decompositions:

43 + 172027 = 172070
61 + 172009 = 172070
181 + 171889 = 172070
193 + 171877 = 172070
271 + 171799 = 172070
277 + 171793 = 172070
307 + 171763 = 172070
313 + 171757 = 172070

Showing the first eight; more decompositions exist.
