Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505034, here are decompositions:

7 + 31505027 = 31505034
31 + 31505003 = 31505034
47 + 31504987 = 31505034
53 + 31504981 = 31505034
83 + 31504951 = 31505034
131 + 31504903 = 31505034
151 + 31504883 = 31505034
233 + 31504801 = 31505034

Showing the first eight; more decompositions exist.
