Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624054, here are decompositions:

41 + 31624013 = 31624054
53 + 31624001 = 31624054
71 + 31623983 = 31624054
83 + 31623971 = 31624054
101 + 31623953 = 31624054
107 + 31623947 = 31624054
167 + 31623887 = 31624054
197 + 31623857 = 31624054

Showing the first eight; more decompositions exist.
