Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31504950, here are decompositions:

7 + 31504943 = 31504950
41 + 31504909 = 31504950
47 + 31504903 = 31504950
67 + 31504883 = 31504950
131 + 31504819 = 31504950
149 + 31504801 = 31504950
151 + 31504799 = 31504950
167 + 31504783 = 31504950

Showing the first eight; more decompositions exist.
