Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31609490, here are decompositions:
- 37 + 31609453 = 31609490
- 97 + 31609393 = 31609490
- 109 + 31609381 = 31609490
- 151 + 31609339 = 31609490
- 223 + 31609267 = 31609490
- 277 + 31609213 = 31609490
- 373 + 31609117 = 31609490
- 379 + 31609111 = 31609490
Showing the first eight; more decompositions exist.
