Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31618852, here are decompositions:

3 + 31618849 = 31618852
29 + 31618823 = 31618852
71 + 31618781 = 31618852
101 + 31618751 = 31618852
149 + 31618703 = 31618852
389 + 31618463 = 31618852
443 + 31618409 = 31618852
449 + 31618403 = 31618852

Showing the first eight; more decompositions exist.
