Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172774, here are decompositions:

23 + 172751 = 172774
53 + 172721 = 172774
101 + 172673 = 172774
131 + 172643 = 172774
167 + 172607 = 172774
191 + 172583 = 172774
233 + 172541 = 172774
257 + 172517 = 172774

Showing the first eight; more decompositions exist.
