Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624294, here are decompositions:

11 + 31624283 = 31624294
17 + 31624277 = 31624294
167 + 31624127 = 31624294
281 + 31624013 = 31624294
293 + 31624001 = 31624294
311 + 31623983 = 31624294
347 + 31623947 = 31624294
563 + 31623731 = 31624294

Showing the first eight; more decompositions exist.
