Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624402, here are decompositions:

53 + 31624349 = 31624402
59 + 31624343 = 31624402
71 + 31624331 = 31624402
389 + 31624013 = 31624402
401 + 31624001 = 31624402
419 + 31623983 = 31624402
431 + 31623971 = 31624402
443 + 31623959 = 31624402

Showing the first eight; more decompositions exist.
