Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535802, here are decompositions:

5 + 31535797 = 31535802
61 + 31535741 = 31535802
131 + 31535671 = 31535802
163 + 31535639 = 31535802
211 + 31535591 = 31535802
251 + 31535551 = 31535802
373 + 31535429 = 31535802
379 + 31535423 = 31535802

Showing the first eight; more decompositions exist.
