Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149380, here are decompositions:
- 3 + 149377 = 149380
- 29 + 149351 = 149380
- 47 + 149333 = 149380
- 71 + 149309 = 149380
- 83 + 149297 = 149380
- 131 + 149249 = 149380
- 167 + 149213 = 149380
- 197 + 149183 = 149380
Showing the first eight; more decompositions exist.
