Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172444, here are decompositions:

3 + 172441 = 172444
5 + 172439 = 172444
11 + 172433 = 172444
17 + 172427 = 172444
23 + 172421 = 172444
71 + 172373 = 172444
101 + 172343 = 172444
113 + 172331 = 172444

Showing the first eight; more decompositions exist.
