Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525544, here are decompositions:

7 + 31525537 = 31525544
67 + 31525477 = 31525544
97 + 31525447 = 31525544
277 + 31525267 = 31525544
283 + 31525261 = 31525544
331 + 31525213 = 31525544
367 + 31525177 = 31525544
577 + 31524967 = 31525544

Showing the first eight; more decompositions exist.
