Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542584, here are decompositions:

37 + 31542547 = 31542584
61 + 31542523 = 31542584
97 + 31542487 = 31542584
127 + 31542457 = 31542584
193 + 31542391 = 31542584
211 + 31542373 = 31542584
421 + 31542163 = 31542584
547 + 31542037 = 31542584

Showing the first eight; more decompositions exist.
