Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615130, here are decompositions:
- 3 + 31615127 = 31615130
- 67 + 31615063 = 31615130
- 241 + 31614889 = 31615130
- 271 + 31614859 = 31615130
- 277 + 31614853 = 31615130
- 397 + 31614733 = 31615130
- 433 + 31614697 = 31615130
- 487 + 31614643 = 31615130
Showing the first eight; more decompositions exist.
