Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71090, here are decompositions:
- 31 + 71059 = 71090
- 67 + 71023 = 71090
- 79 + 71011 = 71090
- 109 + 70981 = 71090
- 139 + 70951 = 71090
- 199 + 70891 = 71090
- 211 + 70879 = 71090
- 223 + 70867 = 71090
Showing the first eight; more decompositions exist.
