Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72544, here are decompositions:
- 11 + 72533 = 72544
- 41 + 72503 = 72544
- 47 + 72497 = 72544
- 83 + 72461 = 72544
- 113 + 72431 = 72544
- 191 + 72353 = 72544
- 257 + 72287 = 72544
- 293 + 72251 = 72544
Showing the first eight; more decompositions exist.
