Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 125826, here are decompositions:
- 5 + 125821 = 125826
- 13 + 125813 = 125826
- 23 + 125803 = 125826
- 37 + 125789 = 125826
- 73 + 125753 = 125826
- 83 + 125743 = 125826
- 89 + 125737 = 125826
- 109 + 125717 = 125826
Showing the first eight; more decompositions exist.
