Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957842, here are decompositions:
- 61 + 4294957781 = 4294957842
- 89 + 4294957753 = 4294957842
- 113 + 4294957729 = 4294957842
- 139 + 4294957703 = 4294957842
- 163 + 4294957679 = 4294957842
- 199 + 4294957643 = 4294957842
- 233 + 4294957609 = 4294957842
- 349 + 4294957493 = 4294957842
Showing the first eight; more decompositions exist.
