Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535852, here are decompositions:

31 + 31535821 = 31535852
43 + 31535809 = 31535852
181 + 31535671 = 31535852
349 + 31535503 = 31535852
433 + 31535419 = 31535852
541 + 31535311 = 31535852
619 + 31535233 = 31535852
709 + 31535143 = 31535852

Showing the first eight; more decompositions exist.
