Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294976820, here are decompositions:
- 23 + 4294976797 = 4294976820
- 47 + 4294976773 = 4294976820
- 89 + 4294976731 = 4294976820
- 97 + 4294976723 = 4294976820
- 103 + 4294976717 = 4294976820
- 181 + 4294976639 = 4294976820
- 193 + 4294976627 = 4294976820
- 241 + 4294976579 = 4294976820
Showing the first eight; more decompositions exist.
