Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535088, here are decompositions:

5 + 31535083 = 31535088
7 + 31535081 = 31535088
29 + 31535059 = 31535088
31 + 31535057 = 31535088
89 + 31534999 = 31535088
107 + 31534981 = 31535088
127 + 31534961 = 31535088
257 + 31534831 = 31535088

Showing the first eight; more decompositions exist.
