Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149488, here are decompositions:
- 29 + 149459 = 149488
- 47 + 149441 = 149488
- 71 + 149417 = 149488
- 89 + 149399 = 149488
- 107 + 149381 = 149488
- 137 + 149351 = 149488
- 179 + 149309 = 149488
- 191 + 149297 = 149488
Showing the first eight; more decompositions exist.
