Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 49690, here are decompositions:
- 23 + 49667 = 49690
- 131 + 49559 = 49690
- 167 + 49523 = 49690
- 191 + 49499 = 49690
- 227 + 49463 = 49690
- 239 + 49451 = 49690
- 257 + 49433 = 49690
- 281 + 49409 = 49690
Showing the first eight; more decompositions exist.
