Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8689472, here are decompositions:
- 19 + 8689453 = 8689472
- 73 + 8689399 = 8689472
- 151 + 8689321 = 8689472
- 163 + 8689309 = 8689472
- 193 + 8689279 = 8689472
- 199 + 8689273 = 8689472
- 223 + 8689249 = 8689472
- 229 + 8689243 = 8689472
Showing the first eight; more decompositions exist.
