Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128044, here are decompositions:
- 11 + 128033 = 128044
- 23 + 128021 = 128044
- 47 + 127997 = 128044
- 71 + 127973 = 128044
- 113 + 127931 = 128044
- 131 + 127913 = 128044
- 167 + 127877 = 128044
- 227 + 127817 = 128044
Showing the first eight; more decompositions exist.
