Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294957890, here are decompositions:
- 29 + 4294957861 = 4294957890
- 31 + 4294957859 = 4294957890
- 37 + 4294957853 = 4294957890
- 109 + 4294957781 = 4294957890
- 137 + 4294957753 = 4294957890
- 173 + 4294957717 = 4294957890
- 191 + 4294957699 = 4294957890
- 193 + 4294957697 = 4294957890
Showing the first eight; more decompositions exist.
