Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31480144, here are decompositions:
- 41 + 31480103 = 31480144
- 53 + 31480091 = 31480144
- 83 + 31480061 = 31480144
- 197 + 31479947 = 31480144
- 263 + 31479881 = 31480144
- 401 + 31479743 = 31480144
- 587 + 31479557 = 31480144
- 593 + 31479551 = 31480144
Showing the first eight; more decompositions exist.
