Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126578, here are decompositions:
- 31 + 126547 = 126578
- 37 + 126541 = 126578
- 61 + 126517 = 126578
- 79 + 126499 = 126578
- 97 + 126481 = 126578
- 157 + 126421 = 126578
- 181 + 126397 = 126578
- 229 + 126349 = 126578
Showing the first eight; more decompositions exist.
