Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974972, here are decompositions:
- 19 + 4294974953 = 4294974972
- 53 + 4294974919 = 4294974972
- 59 + 4294974913 = 4294974972
- 109 + 4294974863 = 4294974972
- 179 + 4294974793 = 4294974972
- 229 + 4294974743 = 4294974972
- 241 + 4294974731 = 4294974972
- 331 + 4294974641 = 4294974972
Showing the first eight; more decompositions exist.
