Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172646, here are decompositions:

3 + 172643 = 172646
13 + 172633 = 172646
43 + 172603 = 172646
73 + 172573 = 172646
127 + 172519 = 172646
139 + 172507 = 172646
157 + 172489 = 172646
223 + 172423 = 172646

Showing the first eight; more decompositions exist.
