Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126490, here are decompositions:
- 3 + 126487 = 126490
- 17 + 126473 = 126490
- 29 + 126461 = 126490
- 47 + 126443 = 126490
- 131 + 126359 = 126490
- 149 + 126341 = 126490
- 167 + 126323 = 126490
- 173 + 126317 = 126490
Showing the first eight; more decompositions exist.
