Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153444, here are decompositions:
- 7 + 153437 = 153444
- 17 + 153427 = 153444
- 23 + 153421 = 153444
- 37 + 153407 = 153444
- 73 + 153371 = 153444
- 101 + 153343 = 153444
- 107 + 153337 = 153444
- 131 + 153313 = 153444
Showing the first eight; more decompositions exist.
