Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144844, here are decompositions:
- 5 + 144839 = 144844
- 53 + 144791 = 144844
- 71 + 144773 = 144844
- 107 + 144737 = 144844
- 113 + 144731 = 144844
- 173 + 144671 = 144844
- 233 + 144611 = 144844
- 251 + 144593 = 144844
Showing the first eight; more decompositions exist.
