Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71270, here are decompositions:
- 7 + 71263 = 71270
- 13 + 71257 = 71270
- 37 + 71233 = 71270
- 61 + 71209 = 71270
- 79 + 71191 = 71270
- 103 + 71167 = 71270
- 109 + 71161 = 71270
- 127 + 71143 = 71270
Showing the first eight; more decompositions exist.
