Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294972538, here are decompositions:
- 97 + 4294972441 = 4294972538
- 127 + 4294972411 = 4294972538
- 271 + 4294972267 = 4294972538
- 331 + 4294972207 = 4294972538
- 421 + 4294972117 = 4294972538
- 487 + 4294972051 = 4294972538
- 499 + 4294972039 = 4294972538
- 547 + 4294971991 = 4294972538
Showing the first eight; more decompositions exist.
