Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294974990, here are decompositions:
- 17 + 4294974973 = 4294974990
- 37 + 4294974953 = 4294974990
- 67 + 4294974923 = 4294974990
- 71 + 4294974919 = 4294974990
- 73 + 4294974917 = 4294974990
- 109 + 4294974881 = 4294974990
- 127 + 4294974863 = 4294974990
- 179 + 4294974811 = 4294974990
Showing the first eight; more decompositions exist.
