Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489330, here are decompositions:
- 71 + 31489259 = 31489330
- 83 + 31489247 = 31489330
- 101 + 31489229 = 31489330
- 113 + 31489217 = 31489330
- 137 + 31489193 = 31489330
- 149 + 31489181 = 31489330
- 233 + 31489097 = 31489330
- 239 + 31489091 = 31489330
Showing the first eight; more decompositions exist.
