Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137378, here are decompositions:
- 19 + 137359 = 137378
- 37 + 137341 = 137378
- 127 + 137251 = 137378
- 139 + 137239 = 137378
- 181 + 137197 = 137378
- 349 + 137029 = 137378
- 379 + 136999 = 137378
- 499 + 136879 = 137378
Showing the first eight; more decompositions exist.
