Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623254, here are decompositions:

31 + 31623223 = 31623254
43 + 31623211 = 31623254
73 + 31623181 = 31623254
193 + 31623061 = 31623254
307 + 31622947 = 31623254
331 + 31622923 = 31623254
373 + 31622881 = 31623254
541 + 31622713 = 31623254

Showing the first eight; more decompositions exist.
