Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31501534, here are decompositions:

3 + 31501531 = 31501534
11 + 31501523 = 31501534
101 + 31501433 = 31501534
107 + 31501427 = 31501534
131 + 31501403 = 31501534
173 + 31501361 = 31501534
443 + 31501091 = 31501534
557 + 31500977 = 31501534

Showing the first eight; more decompositions exist.
