Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525388, here are decompositions:

109 + 31525279 = 31525388
127 + 31525261 = 31525388
211 + 31525177 = 31525388
397 + 31524991 = 31525388
421 + 31524967 = 31525388
919 + 31524469 = 31525388
1087 + 31524301 = 31525388
1117 + 31524271 = 31525388

Showing the first eight; more decompositions exist.
