Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31474390, here are decompositions:
- 47 + 31474343 = 31474390
- 71 + 31474319 = 31474390
- 83 + 31474307 = 31474390
- 89 + 31474301 = 31474390
- 137 + 31474253 = 31474390
- 173 + 31474217 = 31474390
- 317 + 31474073 = 31474390
- 347 + 31474043 = 31474390
Showing the first eight; more decompositions exist.
