Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535710, here are decompositions:

29 + 31535681 = 31535710
53 + 31535657 = 31535710
71 + 31535639 = 31535710
281 + 31535429 = 31535710
293 + 31535417 = 31535710
383 + 31535327 = 31535710
389 + 31535321 = 31535710
491 + 31535219 = 31535710

Showing the first eight; more decompositions exist.
