Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454804, here are decompositions:

67 + 31454737 = 31454804
103 + 31454701 = 31454804
151 + 31454653 = 31454804
307 + 31454497 = 31454804
373 + 31454431 = 31454804
421 + 31454383 = 31454804
541 + 31454263 = 31454804
607 + 31454197 = 31454804

Showing the first eight; more decompositions exist.
