Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454756, here are decompositions:

19 + 31454737 = 31454756
103 + 31454653 = 31454756
367 + 31454389 = 31454756
373 + 31454383 = 31454756
379 + 31454377 = 31454756
607 + 31454149 = 31454756
673 + 31454083 = 31454756
733 + 31454023 = 31454756

Showing the first eight; more decompositions exist.
