Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125228, here are decompositions:
- 7 + 125221 = 125228
- 31 + 125197 = 125228
- 79 + 125149 = 125228
- 97 + 125131 = 125228
- 109 + 125119 = 125228
- 127 + 125101 = 125228
- 199 + 125029 = 125228
- 211 + 125017 = 125228
Showing the first eight; more decompositions exist.
