Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137278, here are decompositions:
- 5 + 137273 = 137278
- 59 + 137219 = 137278
- 101 + 137177 = 137278
- 131 + 137147 = 137278
- 191 + 137087 = 137278
- 389 + 136889 = 137278
- 419 + 136859 = 137278
- 467 + 136811 = 137278
Showing the first eight; more decompositions exist.
