Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535154, here are decompositions:

11 + 31535143 = 31535154
23 + 31535131 = 31535154
31 + 31535123 = 31535154
41 + 31535113 = 31535154
47 + 31535107 = 31535154
71 + 31535083 = 31535154
73 + 31535081 = 31535154
97 + 31535057 = 31535154

Showing the first eight; more decompositions exist.
