Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624318, here are decompositions:

41 + 31624277 = 31624318
101 + 31624217 = 31624318
191 + 31624127 = 31624318
317 + 31624001 = 31624318
347 + 31623971 = 31624318
359 + 31623959 = 31624318
389 + 31623929 = 31624318
431 + 31623887 = 31624318

Showing the first eight; more decompositions exist.
