Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525358, here are decompositions:

79 + 31525279 = 31525358
97 + 31525261 = 31525358
157 + 31525201 = 31525358
181 + 31525177 = 31525358
331 + 31525027 = 31525358
367 + 31524991 = 31525358
421 + 31524937 = 31525358
751 + 31524607 = 31525358

Showing the first eight; more decompositions exist.
