Goldbach decomposition
Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294975140, here are decompositions:
- 17 + 4294975123 = 4294975140
- 23 + 4294975117 = 4294975140
- 31 + 4294975109 = 4294975140
- 47 + 4294975093 = 4294975140
- 61 + 4294975079 = 4294975140
- 83 + 4294975057 = 4294975140
- 89 + 4294975051 = 4294975140
- 97 + 4294975043 = 4294975140
Showing the first eight; more decompositions exist.
