Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725488, here are decompositions:
- 7 + 8725481 = 8725488
- 29 + 8725459 = 8725488
- 59 + 8725429 = 8725488
- 67 + 8725421 = 8725488
- 89 + 8725399 = 8725488
- 97 + 8725391 = 8725488
- 127 + 8725361 = 8725488
- 131 + 8725357 = 8725488
Showing the first eight; more decompositions exist.
