Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 75722, here are decompositions:
- 13 + 75709 = 75722
- 19 + 75703 = 75722
- 43 + 75679 = 75722
- 103 + 75619 = 75722
- 139 + 75583 = 75722
- 151 + 75571 = 75722
- 181 + 75541 = 75722
- 211 + 75511 = 75722
Showing the first eight; more decompositions exist.
