Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 72844, here are decompositions:
- 47 + 72797 = 72844
- 137 + 72707 = 72844
- 173 + 72671 = 72844
- 197 + 72647 = 72844
- 227 + 72617 = 72844
- 293 + 72551 = 72844
- 311 + 72533 = 72844
- 347 + 72497 = 72844
Showing the first eight; more decompositions exist.
