Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31540996, here are decompositions:

5 + 31540991 = 31540996
17 + 31540979 = 31540996
173 + 31540823 = 31540996
269 + 31540727 = 31540996
317 + 31540679 = 31540996
353 + 31540643 = 31540996
359 + 31540637 = 31540996
467 + 31540529 = 31540996

Showing the first eight; more decompositions exist.
