Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535954, here are decompositions:

7 + 31535947 = 31535954
13 + 31535941 = 31535954
127 + 31535827 = 31535954
157 + 31535797 = 31535954
283 + 31535671 = 31535954
487 + 31535467 = 31535954
577 + 31535377 = 31535954
613 + 31535341 = 31535954

Showing the first eight; more decompositions exist.
