Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71272, here are decompositions:
- 11 + 71261 = 71272
- 23 + 71249 = 71272
- 101 + 71171 = 71272
- 191 + 71081 = 71272
- 233 + 71039 = 71272
- 281 + 70991 = 71272
- 293 + 70979 = 71272
- 353 + 70919 = 71272
Showing the first eight; more decompositions exist.
