Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534802, here are decompositions:

3 + 31534799 = 31534802
73 + 31534729 = 31534802
151 + 31534651 = 31534802
241 + 31534561 = 31534802
373 + 31534429 = 31534802
379 + 31534423 = 31534802
433 + 31534369 = 31534802
571 + 31534231 = 31534802

Showing the first eight; more decompositions exist.
