Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 71492, here are decompositions:
- 13 + 71479 = 71492
- 19 + 71473 = 71492
- 73 + 71419 = 71492
- 79 + 71413 = 71492
- 103 + 71389 = 71492
- 139 + 71353 = 71492
- 151 + 71341 = 71492
- 163 + 71329 = 71492
Showing the first eight; more decompositions exist.
