Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294971218, here are decompositions:
- 19 + 4294971199 = 4294971218
- 67 + 4294971151 = 4294971218
- 379 + 4294970839 = 4294971218
- 457 + 4294970761 = 4294971218
- 751 + 4294970467 = 4294971218
- 1069 + 4294970149 = 4294971218
- 1129 + 4294970089 = 4294971218
- 1321 + 4294969897 = 4294971218
Showing the first eight; more decompositions exist.
