Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137390, here are decompositions:
- 3 + 137387 = 137390
- 7 + 137383 = 137390
- 31 + 137359 = 137390
- 37 + 137353 = 137390
- 139 + 137251 = 137390
- 151 + 137239 = 137390
- 181 + 137209 = 137390
- 193 + 137197 = 137390
Showing the first eight; more decompositions exist.
