Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294968878, here are decompositions:
- 139 + 4294968739 = 4294968878
- 181 + 4294968697 = 4294968878
- 241 + 4294968637 = 4294968878
- 271 + 4294968607 = 4294968878
- 397 + 4294968481 = 4294968878
- 547 + 4294968331 = 4294968878
- 691 + 4294968187 = 4294968878
- 751 + 4294968127 = 4294968878
Showing the first eight; more decompositions exist.
