Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137438, here are decompositions:
- 79 + 137359 = 137438
- 97 + 137341 = 137438
- 199 + 137239 = 137438
- 229 + 137209 = 137438
- 241 + 137197 = 137438
- 307 + 137131 = 137438
- 349 + 137089 = 137438
- 409 + 137029 = 137438
Showing the first eight; more decompositions exist.
