Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8750478, here are decompositions:
- 7 + 8750471 = 8750478
- 31 + 8750447 = 8750478
- 101 + 8750377 = 8750478
- 109 + 8750369 = 8750478
- 127 + 8750351 = 8750478
- 131 + 8750347 = 8750478
- 137 + 8750341 = 8750478
- 157 + 8750321 = 8750478
Showing the first eight; more decompositions exist.
