Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957642, here are decompositions:
- 89 + 4294957553 = 4294957642
- 149 + 4294957493 = 4294957642
- 293 + 4294957349 = 4294957642
- 653 + 4294956989 = 4294957642
- 719 + 4294956923 = 4294957642
- 761 + 4294956881 = 4294957642
- 809 + 4294956833 = 4294957642
- 953 + 4294956689 = 4294957642
Showing the first eight; more decompositions exist.
