Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71120, here are decompositions:
- 31 + 71089 = 71120
- 61 + 71059 = 71120
- 97 + 71023 = 71120
- 109 + 71011 = 71120
- 139 + 70981 = 71120
- 151 + 70969 = 71120
- 163 + 70957 = 71120
- 199 + 70921 = 71120
Showing the first eight; more decompositions exist.
