Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542466, here are decompositions:

29 + 31542437 = 31542466
47 + 31542419 = 31542466
89 + 31542377 = 31542466
107 + 31542359 = 31542466
233 + 31542233 = 31542466
269 + 31542197 = 31542466
317 + 31542149 = 31542466
353 + 31542113 = 31542466

Showing the first eight; more decompositions exist.
