Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31530802, here are decompositions:

3 + 31530799 = 31530802
5 + 31530797 = 31530802
29 + 31530773 = 31530802
89 + 31530713 = 31530802
101 + 31530701 = 31530802
383 + 31530419 = 31530802
419 + 31530383 = 31530802
461 + 31530341 = 31530802

Showing the first eight; more decompositions exist.
