Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971940, here are decompositions:
- 3 + 4294971937 = 4294971940
- 11 + 4294971929 = 4294971940
- 383 + 4294971557 = 4294971940
- 443 + 4294971497 = 4294971940
- 449 + 4294971491 = 4294971940
- 509 + 4294971431 = 4294971940
- 563 + 4294971377 = 4294971940
- 617 + 4294971323 = 4294971940
Showing the first eight; more decompositions exist.
