Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543852, here are decompositions:

5 + 31543847 = 31543852
23 + 31543829 = 31543852
83 + 31543769 = 31543852
89 + 31543763 = 31543852
101 + 31543751 = 31543852
191 + 31543661 = 31543852
281 + 31543571 = 31543852
401 + 31543451 = 31543852

Showing the first eight; more decompositions exist.
