Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172970, here are decompositions:

37 + 172933 = 172970
103 + 172867 = 172970
163 + 172807 = 172970
211 + 172759 = 172970
229 + 172741 = 172970
283 + 172687 = 172970
307 + 172663 = 172970
313 + 172657 = 172970

Showing the first eight; more decompositions exist.
