Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172862, here are decompositions:

3 + 172859 = 172862
13 + 172849 = 172862
61 + 172801 = 172862
103 + 172759 = 172862
181 + 172681 = 172862
199 + 172663 = 172862
229 + 172633 = 172862
373 + 172489 = 172862

Showing the first eight; more decompositions exist.
