Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454126, here are decompositions:

3 + 31454123 = 31454126
43 + 31454083 = 31454126
73 + 31454053 = 31454126
103 + 31454023 = 31454126
157 + 31453969 = 31454126
229 + 31453897 = 31454126
313 + 31453813 = 31454126
619 + 31453507 = 31454126

Showing the first eight; more decompositions exist.
