Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31042, here are decompositions:
- 3 + 31039 = 31042
- 23 + 31019 = 31042
- 29 + 31013 = 31042
- 59 + 30983 = 31042
- 71 + 30971 = 31042
- 101 + 30941 = 31042
- 131 + 30911 = 31042
- 149 + 30893 = 31042
Showing the first eight; more decompositions exist.
