Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972042, here are decompositions:
- 3 + 4294972039 = 4294972042
- 5 + 4294972037 = 4294972042
- 113 + 4294971929 = 4294972042
- 479 + 4294971563 = 4294972042
- 653 + 4294971389 = 4294972042
- 719 + 4294971323 = 4294972042
- 773 + 4294971269 = 4294972042
- 821 + 4294971221 = 4294972042
Showing the first eight; more decompositions exist.
