Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507476, here are decompositions:
- 17 + 31507459 = 31507476
- 73 + 31507403 = 31507476
- 109 + 31507367 = 31507476
- 113 + 31507363 = 31507476
- 157 + 31507319 = 31507476
- 179 + 31507297 = 31507476
- 193 + 31507283 = 31507476
- 233 + 31507243 = 31507476
Showing the first eight; more decompositions exist.
