Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525738, here are decompositions:

89 + 31525649 = 31525738
131 + 31525607 = 31525738
137 + 31525601 = 31525738
149 + 31525589 = 31525738
239 + 31525499 = 31525738
317 + 31525421 = 31525738
359 + 31525379 = 31525738
449 + 31525289 = 31525738

Showing the first eight; more decompositions exist.
