Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75688, here are decompositions:
- 5 + 75683 = 75688
- 29 + 75659 = 75688
- 47 + 75641 = 75688
- 59 + 75629 = 75688
- 71 + 75617 = 75688
- 131 + 75557 = 75688
- 149 + 75539 = 75688
- 167 + 75521 = 75688
Showing the first eight; more decompositions exist.
