Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972442, here are decompositions:
- 31 + 4294972411 = 4294972442
- 109 + 4294972333 = 4294972442
- 151 + 4294972291 = 4294972442
- 199 + 4294972243 = 4294972442
- 349 + 4294972093 = 4294972442
- 373 + 4294972069 = 4294972442
- 379 + 4294972063 = 4294972442
- 499 + 4294971943 = 4294972442
Showing the first eight; more decompositions exist.
