Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543532, here are decompositions:

3 + 31543529 = 31543532
43 + 31543489 = 31543532
79 + 31543453 = 31543532
103 + 31543429 = 31543532
313 + 31543219 = 31543532
463 + 31543069 = 31543532
523 + 31543009 = 31543532
541 + 31542991 = 31543532

Showing the first eight; more decompositions exist.
