Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294958642, here are decompositions:
- 31 + 4294958611 = 4294958642
- 103 + 4294958539 = 4294958642
- 181 + 4294958461 = 4294958642
- 193 + 4294958449 = 4294958642
- 199 + 4294958443 = 4294958642
- 241 + 4294958401 = 4294958642
- 313 + 4294958329 = 4294958642
- 571 + 4294958071 = 4294958642
Showing the first eight; more decompositions exist.
