Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738408, here are decompositions:
- 31 + 8738377 = 8738408
- 109 + 8738299 = 8738408
- 127 + 8738281 = 8738408
- 181 + 8738227 = 8738408
- 199 + 8738209 = 8738408
- 307 + 8738101 = 8738408
- 337 + 8738071 = 8738408
- 397 + 8738011 = 8738408
Showing the first eight; more decompositions exist.
