Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516430, here are decompositions:
- 3 + 31516427 = 31516430
- 7 + 31516423 = 31516430
- 19 + 31516411 = 31516430
- 73 + 31516357 = 31516430
- 97 + 31516333 = 31516430
- 103 + 31516327 = 31516430
- 193 + 31516237 = 31516430
- 229 + 31516201 = 31516430
Showing the first eight; more decompositions exist.
