Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31526042, here are decompositions:
- 61 + 31525981 = 31526042
- 139 + 31525903 = 31526042
- 151 + 31525891 = 31526042
- 193 + 31525849 = 31526042
- 271 + 31525771 = 31526042
- 433 + 31525609 = 31526042
- 439 + 31525603 = 31526042
- 829 + 31525213 = 31526042
Showing the first eight; more decompositions exist.
