Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542404, here are decompositions:

7 + 31542397 = 31542404
13 + 31542391 = 31542404
31 + 31542373 = 31542404
241 + 31542163 = 31542404
337 + 31542067 = 31542404
367 + 31542037 = 31542404
373 + 31542031 = 31542404
433 + 31541971 = 31542404

Showing the first eight; more decompositions exist.
