Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454772, here are decompositions:

31 + 31454741 = 31454772
71 + 31454701 = 31454772
103 + 31454669 = 31454772
311 + 31454461 = 31454772
331 + 31454441 = 31454772
383 + 31454389 = 31454772
389 + 31454383 = 31454772
421 + 31454351 = 31454772

Showing the first eight; more decompositions exist.
