Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147388246, here are decompositions:
- 5 + 2147388241 = 2147388246
- 7 + 2147388239 = 2147388246
- 13 + 2147388233 = 2147388246
- 37 + 2147388209 = 2147388246
- 67 + 2147388179 = 2147388246
- 127 + 2147388119 = 2147388246
- 139 + 2147388107 = 2147388246
- 149 + 2147388097 = 2147388246
Showing the first eight; more decompositions exist.
