Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535838, here are decompositions:

7 + 31535831 = 31535838
11 + 31535827 = 31535838
17 + 31535821 = 31535838
29 + 31535809 = 31535838
41 + 31535797 = 31535838
97 + 31535741 = 31535838
157 + 31535681 = 31535838
167 + 31535671 = 31535838

Showing the first eight; more decompositions exist.
