Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172790, here are decompositions:

3 + 172787 = 172790
31 + 172759 = 172790
73 + 172717 = 172790
103 + 172687 = 172790
109 + 172681 = 172790
127 + 172663 = 172790
157 + 172633 = 172790
193 + 172597 = 172790

Showing the first eight; more decompositions exist.
