Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525104, here are decompositions:

67 + 31525037 = 31525104
73 + 31525031 = 31525104
97 + 31525007 = 31525104
113 + 31524991 = 31525104
137 + 31524967 = 31525104
167 + 31524937 = 31525104
211 + 31524893 = 31525104
241 + 31524863 = 31525104

Showing the first eight; more decompositions exist.
