Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157644, here are decompositions:
- 5 + 157639 = 157644
- 7 + 157637 = 157644
- 17 + 157627 = 157644
- 73 + 157571 = 157644
- 83 + 157561 = 157644
- 101 + 157543 = 157644
- 131 + 157513 = 157644
- 167 + 157477 = 157644
Showing the first eight; more decompositions exist.
