Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971880, here are decompositions:
- 317 + 4294971563 = 4294971880
- 383 + 4294971497 = 4294971880
- 389 + 4294971491 = 4294971880
- 449 + 4294971431 = 4294971880
- 491 + 4294971389 = 4294971880
- 503 + 4294971377 = 4294971880
- 557 + 4294971323 = 4294971880
- 653 + 4294971227 = 4294971880
Showing the first eight; more decompositions exist.
