Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172926, here are decompositions:

43 + 172883 = 172926
59 + 172867 = 172926
67 + 172859 = 172926
73 + 172853 = 172926
97 + 172829 = 172926
139 + 172787 = 172926
167 + 172759 = 172926
239 + 172687 = 172926

Showing the first eight; more decompositions exist.
