Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71244, here are decompositions:
- 7 + 71237 = 71244
- 11 + 71233 = 71244
- 53 + 71191 = 71244
- 73 + 71171 = 71244
- 83 + 71161 = 71244
- 97 + 71147 = 71244
- 101 + 71143 = 71244
- 163 + 71081 = 71244
Showing the first eight; more decompositions exist.
