Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455374, here are decompositions:
- 3 + 31455371 = 31455374
- 7 + 31455367 = 31455374
- 61 + 31455313 = 31455374
- 73 + 31455301 = 31455374
- 103 + 31455271 = 31455374
- 151 + 31455223 = 31455374
- 271 + 31455103 = 31455374
- 421 + 31454953 = 31455374
Showing the first eight; more decompositions exist.
