Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489202, here are decompositions:

139 + 31489063 = 31489202
193 + 31489009 = 31489202
211 + 31488991 = 31489202
223 + 31488979 = 31489202
271 + 31488931 = 31489202
571 + 31488631 = 31489202
709 + 31488493 = 31489202
733 + 31488469 = 31489202

Showing the first eight; more decompositions exist.
