Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155698, here are decompositions:
- 5 + 155693 = 155698
- 41 + 155657 = 155698
- 71 + 155627 = 155698
- 89 + 155609 = 155698
- 197 + 155501 = 155698
- 311 + 155387 = 155698
- 317 + 155381 = 155698
- 467 + 155231 = 155698
Showing the first eight; more decompositions exist.
