Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497430, here are decompositions:
- 71 + 31497359 = 31497430
- 89 + 31497341 = 31497430
- 131 + 31497299 = 31497430
- 137 + 31497293 = 31497430
- 179 + 31497251 = 31497430
- 347 + 31497083 = 31497430
- 359 + 31497071 = 31497430
- 467 + 31496963 = 31497430
Showing the first eight; more decompositions exist.
