Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624172, here are decompositions:
- 31 + 31624141 = 31624172
- 43 + 31624129 = 31624172
- 103 + 31624069 = 31624172
- 193 + 31623979 = 31624172
- 241 + 31623931 = 31624172
- 271 + 31623901 = 31624172
- 661 + 31623511 = 31624172
- 673 + 31623499 = 31624172
Showing the first eight; more decompositions exist.
