Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31624174, here are decompositions:

47 + 31624127 = 31624174
173 + 31624001 = 31624174
191 + 31623983 = 31624174
227 + 31623947 = 31624174
317 + 31623857 = 31624174
353 + 31623821 = 31624174
443 + 31623731 = 31624174
467 + 31623707 = 31624174

Showing the first eight; more decompositions exist.
