Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528060, here are decompositions:

23 + 31528037 = 31528060
41 + 31528019 = 31528060
59 + 31528001 = 31528060
173 + 31527887 = 31528060
233 + 31527827 = 31528060
359 + 31527701 = 31528060
383 + 31527677 = 31528060
401 + 31527659 = 31528060

Showing the first eight; more decompositions exist.
