Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542470, here are decompositions:

13 + 31542457 = 31542470
31 + 31542439 = 31542470
73 + 31542397 = 31542470
79 + 31542391 = 31542470
97 + 31542373 = 31542470
241 + 31542229 = 31542470
307 + 31542163 = 31542470
367 + 31542103 = 31542470

Showing the first eight; more decompositions exist.
