Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567352, here are decompositions:

73 + 31567279 = 31567352
139 + 31567213 = 31567352
199 + 31567153 = 31567352
373 + 31566979 = 31567352
379 + 31566973 = 31567352
433 + 31566919 = 31567352
643 + 31566709 = 31567352
811 + 31566541 = 31567352

Showing the first eight; more decompositions exist.
