Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88720, here are decompositions:
- 53 + 88667 = 88720
- 59 + 88661 = 88720
- 113 + 88607 = 88720
- 131 + 88589 = 88720
- 173 + 88547 = 88720
- 197 + 88523 = 88720
- 227 + 88493 = 88720
- 251 + 88469 = 88720
Showing the first eight; more decompositions exist.
