Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155446, here are decompositions:
- 3 + 155443 = 155446
- 23 + 155423 = 155446
- 47 + 155399 = 155446
- 59 + 155387 = 155446
- 113 + 155333 = 155446
- 227 + 155219 = 155446
- 293 + 155153 = 155446
- 359 + 155087 = 155446
Showing the first eight; more decompositions exist.
