Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489318, here are decompositions:
- 59 + 31489259 = 31489318
- 71 + 31489247 = 31489318
- 89 + 31489229 = 31489318
- 101 + 31489217 = 31489318
- 137 + 31489181 = 31489318
- 149 + 31489169 = 31489318
- 227 + 31489091 = 31489318
- 239 + 31489079 = 31489318
Showing the first eight; more decompositions exist.
