Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541100, here are decompositions:
- 29 + 31541071 = 31541100
- 53 + 31541047 = 31541100
- 61 + 31541039 = 31541100
- 79 + 31541021 = 31541100
- 83 + 31541017 = 31541100
- 109 + 31540991 = 31541100
- 139 + 31540961 = 31541100
- 179 + 31540921 = 31541100
Showing the first eight; more decompositions exist.
