Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988632, here are decompositions:
- 41 + 988591 = 988632
- 53 + 988579 = 988632
- 61 + 988571 = 988632
- 83 + 988549 = 988632
- 131 + 988501 = 988632
- 149 + 988483 = 988632
- 173 + 988459 = 988632
- 179 + 988453 = 988632
Showing the first eight; more decompositions exist.
