Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534032, here are decompositions:

53 + 31533979 = 31534032
73 + 31533959 = 31534032
83 + 31533949 = 31534032
109 + 31533923 = 31534032
113 + 31533919 = 31534032
193 + 31533839 = 31534032
199 + 31533833 = 31534032
241 + 31533791 = 31534032

Showing the first eight; more decompositions exist.
