Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462200, here are decompositions:
- 59 + 31462141 = 31462200
- 67 + 31462133 = 31462200
- 73 + 31462127 = 31462200
- 97 + 31462103 = 31462200
- 131 + 31462069 = 31462200
- 179 + 31462021 = 31462200
- 193 + 31462007 = 31462200
- 197 + 31462003 = 31462200
Showing the first eight; more decompositions exist.
