Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527324, here are decompositions:
- 7 + 31527317 = 31527324
- 13 + 31527311 = 31527324
- 47 + 31527277 = 31527324
- 71 + 31527253 = 31527324
- 113 + 31527211 = 31527324
- 131 + 31527193 = 31527324
- 151 + 31527173 = 31527324
- 167 + 31527157 = 31527324
Showing the first eight; more decompositions exist.
