Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535300, here are decompositions:

37 + 31535263 = 31535300
67 + 31535233 = 31535300
73 + 31535227 = 31535300
127 + 31535173 = 31535300
157 + 31535143 = 31535300
193 + 31535107 = 31535300
241 + 31535059 = 31535300
421 + 31534879 = 31535300

Showing the first eight; more decompositions exist.
