Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31611492, here are decompositions:
- 5 + 31611487 = 31611492
- 19 + 31611473 = 31611492
- 53 + 31611439 = 31611492
- 89 + 31611403 = 31611492
- 113 + 31611379 = 31611492
- 151 + 31611341 = 31611492
- 163 + 31611329 = 31611492
- 173 + 31611319 = 31611492
Showing the first eight; more decompositions exist.
