Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8736390, here are decompositions:
- 23 + 8736367 = 8736390
- 67 + 8736323 = 8736390
- 127 + 8736263 = 8736390
- 167 + 8736223 = 8736390
- 181 + 8736209 = 8736390
- 191 + 8736199 = 8736390
- 199 + 8736191 = 8736390
- 211 + 8736179 = 8736390
Showing the first eight; more decompositions exist.
