Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31487752, here are decompositions:
- 71 + 31487681 = 31487752
- 89 + 31487663 = 31487752
- 239 + 31487513 = 31487752
- 281 + 31487471 = 31487752
- 383 + 31487369 = 31487752
- 389 + 31487363 = 31487752
- 521 + 31487231 = 31487752
- 599 + 31487153 = 31487752
Showing the first eight; more decompositions exist.
