Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535948, here are decompositions:

7 + 31535941 = 31535948
127 + 31535821 = 31535948
139 + 31535809 = 31535948
151 + 31535797 = 31535948
277 + 31535671 = 31535948
397 + 31535551 = 31535948
571 + 31535377 = 31535948
607 + 31535341 = 31535948

Showing the first eight; more decompositions exist.
