Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972784, here are decompositions:
- 127 + 4294972657 = 4294972784
- 181 + 4294972603 = 4294972784
- 373 + 4294972411 = 4294972784
- 433 + 4294972351 = 4294972784
- 541 + 4294972243 = 4294972784
- 547 + 4294972237 = 4294972784
- 577 + 4294972207 = 4294972784
- 691 + 4294972093 = 4294972784
Showing the first eight; more decompositions exist.
