Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525302, here are decompositions:

13 + 31525289 = 31525302
19 + 31525283 = 31525302
23 + 31525279 = 31525302
41 + 31525261 = 31525302
59 + 31525243 = 31525302
73 + 31525229 = 31525302
89 + 31525213 = 31525302
101 + 31525201 = 31525302

Showing the first eight; more decompositions exist.
