Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 69990, here are decompositions:
- 31 + 69959 = 69990
- 59 + 69931 = 69990
- 61 + 69929 = 69990
- 79 + 69911 = 69990
- 113 + 69877 = 69990
- 131 + 69859 = 69990
- 157 + 69833 = 69990
- 163 + 69827 = 69990
Showing the first eight; more decompositions exist.
