Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71444, here are decompositions:
- 7 + 71437 = 71444
- 31 + 71413 = 71444
- 97 + 71347 = 71444
- 103 + 71341 = 71444
- 127 + 71317 = 71444
- 151 + 71293 = 71444
- 157 + 71287 = 71444
- 181 + 71263 = 71444
Showing the first eight; more decompositions exist.
