Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535432, here are decompositions:

3 + 31535429 = 31535432
13 + 31535419 = 31535432
199 + 31535233 = 31535432
349 + 31535083 = 31535432
373 + 31535059 = 31535432
421 + 31535011 = 31535432
433 + 31534999 = 31535432
601 + 31534831 = 31535432

Showing the first eight; more decompositions exist.
