Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294967642, here are decompositions:
- 3 + 4294967639 = 4294967642
- 73 + 4294967569 = 4294967642
- 79 + 4294967563 = 4294967642
- 103 + 4294967539 = 4294967642
- 271 + 4294967371 = 4294967642
- 331 + 4294967311 = 4294967642
- 499 + 4294967143 = 4294967642
- 613 + 4294967029 = 4294967642
Showing the first eight; more decompositions exist.
