Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535122, here are decompositions:

41 + 31535081 = 31535122
89 + 31535033 = 31535122
251 + 31534871 = 31535122
383 + 31534739 = 31535122
431 + 31534691 = 31535122
491 + 31534631 = 31535122
569 + 31534553 = 31535122
821 + 31534301 = 31535122

Showing the first eight; more decompositions exist.
