Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532050, here are decompositions:

29 + 31532021 = 31532050
47 + 31532003 = 31532050
83 + 31531967 = 31532050
167 + 31531883 = 31532050
233 + 31531817 = 31532050
383 + 31531667 = 31532050
401 + 31531649 = 31532050
593 + 31531457 = 31532050

Showing the first eight; more decompositions exist.
