Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958158, here are decompositions:
- 59 + 4294958099 = 4294958158
- 89 + 4294958069 = 4294958158
- 107 + 4294958051 = 4294958158
- 131 + 4294958027 = 4294958158
- 167 + 4294957991 = 4294958158
- 317 + 4294957841 = 4294958158
- 461 + 4294957697 = 4294958158
- 479 + 4294957679 = 4294958158
Showing the first eight; more decompositions exist.
