Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126898, here are decompositions:
- 41 + 126857 = 126898
- 47 + 126851 = 126898
- 59 + 126839 = 126898
- 71 + 126827 = 126898
- 137 + 126761 = 126898
- 179 + 126719 = 126898
- 257 + 126641 = 126898
- 347 + 126551 = 126898
Showing the first eight; more decompositions exist.
