Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541070, here are decompositions:
- 19 + 31541051 = 31541070
- 23 + 31541047 = 31541070
- 31 + 31541039 = 31541070
- 53 + 31541017 = 31541070
- 79 + 31540991 = 31541070
- 109 + 31540961 = 31541070
- 131 + 31540939 = 31541070
- 149 + 31540921 = 31541070
Showing the first eight; more decompositions exist.
