Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31536040, here are decompositions:

23 + 31536017 = 31536040
59 + 31535981 = 31536040
101 + 31535939 = 31536040
131 + 31535909 = 31536040
293 + 31535747 = 31536040
359 + 31535681 = 31536040
383 + 31535657 = 31536040
401 + 31535639 = 31536040

Showing the first eight; more decompositions exist.
