Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8737378, here are decompositions:
- 5 + 8737373 = 8737378
- 29 + 8737349 = 8737378
- 101 + 8737277 = 8737378
- 107 + 8737271 = 8737378
- 131 + 8737247 = 8737378
- 179 + 8737199 = 8737378
- 239 + 8737139 = 8737378
- 281 + 8737097 = 8737378
Showing the first eight; more decompositions exist.
