Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31454918, here are decompositions:

37 + 31454881 = 31454918
109 + 31454809 = 31454918
181 + 31454737 = 31454918
331 + 31454587 = 31454918
421 + 31454497 = 31454918
457 + 31454461 = 31454918
487 + 31454431 = 31454918
541 + 31454377 = 31454918

Showing the first eight; more decompositions exist.
