Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541452, here are decompositions:
- 3 + 31541449 = 31541452
- 23 + 31541429 = 31541452
- 53 + 31541399 = 31541452
- 311 + 31541141 = 31541452
- 401 + 31541051 = 31541452
- 431 + 31541021 = 31541452
- 461 + 31540991 = 31541452
- 491 + 31540961 = 31541452
Showing the first eight; more decompositions exist.
