Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620788, here are decompositions:
- 37 + 31620751 = 31620788
- 79 + 31620709 = 31620788
- 109 + 31620679 = 31620788
- 127 + 31620661 = 31620788
- 211 + 31620577 = 31620788
- 271 + 31620517 = 31620788
- 307 + 31620481 = 31620788
- 379 + 31620409 = 31620788
Showing the first eight; more decompositions exist.
