Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 126478, here are decompositions:
- 5 + 126473 = 126478
- 17 + 126461 = 126478
- 137 + 126341 = 126478
- 167 + 126311 = 126478
- 251 + 126227 = 126478
- 347 + 126131 = 126478
- 431 + 126047 = 126478
- 467 + 126011 = 126478
Showing the first eight; more decompositions exist.
