Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 127198, here are decompositions:
- 41 + 127157 = 127198
- 59 + 127139 = 127198
- 167 + 127031 = 127198
- 347 + 126851 = 127198
- 359 + 126839 = 127198
- 479 + 126719 = 127198
- 557 + 126641 = 127198
- 587 + 126611 = 127198
Showing the first eight; more decompositions exist.
