Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535126, here are decompositions:

3 + 31535123 = 31535126
13 + 31535113 = 31535126
19 + 31535107 = 31535126
43 + 31535083 = 31535126
67 + 31535059 = 31535126
127 + 31534999 = 31535126
307 + 31534819 = 31535126
373 + 31534753 = 31535126

Showing the first eight; more decompositions exist.
