Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 151738, here are decompositions:
- 5 + 151733 = 151738
- 71 + 151667 = 151738
- 101 + 151637 = 151738
- 107 + 151631 = 151738
- 131 + 151607 = 151738
- 239 + 151499 = 151738
- 347 + 151391 = 151738
- 359 + 151379 = 151738
Showing the first eight; more decompositions exist.
