Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957242, here are decompositions:
- 53 + 4294957189 = 4294957242
- 139 + 4294957103 = 4294957242
- 293 + 4294956949 = 4294957242
- 353 + 4294956889 = 4294957242
- 379 + 4294956863 = 4294957242
- 409 + 4294956833 = 4294957242
- 449 + 4294956793 = 4294957242
- 491 + 4294956751 = 4294957242
Showing the first eight; more decompositions exist.
