Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31559052, here are decompositions:

59 + 31558993 = 31559052
79 + 31558973 = 31559052
89 + 31558963 = 31559052
113 + 31558939 = 31559052
193 + 31558859 = 31559052
229 + 31558823 = 31559052
233 + 31558819 = 31559052
263 + 31558789 = 31559052

Showing the first eight; more decompositions exist.
