Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31525634, here are decompositions:

31 + 31525603 = 31525634
67 + 31525567 = 31525634
97 + 31525537 = 31525634
157 + 31525477 = 31525634
367 + 31525267 = 31525634
373 + 31525261 = 31525634
421 + 31525213 = 31525634
433 + 31525201 = 31525634

Showing the first eight; more decompositions exist.
