Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534890, here are decompositions:

11 + 31534879 = 31534890
17 + 31534873 = 31534890
19 + 31534871 = 31534890
59 + 31534831 = 31534890
71 + 31534819 = 31534890
89 + 31534801 = 31534890
103 + 31534787 = 31534890
137 + 31534753 = 31534890

Showing the first eight; more decompositions exist.
