Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8637402, here are decompositions:
- 23 + 8637379 = 8637402
- 29 + 8637373 = 8637402
- 61 + 8637341 = 8637402
- 79 + 8637323 = 8637402
- 83 + 8637319 = 8637402
- 101 + 8637301 = 8637402
- 113 + 8637289 = 8637402
- 139 + 8637263 = 8637402
Showing the first eight; more decompositions exist.
