Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 172544, here are decompositions:

3 + 172541 = 172544
37 + 172507 = 172544
103 + 172441 = 172544
193 + 172351 = 172544
223 + 172321 = 172544
331 + 172213 = 172544
373 + 172171 = 172544
397 + 172147 = 172544

Showing the first eight; more decompositions exist.
