Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31467554, here are decompositions:

3 + 31467551 = 31467554
73 + 31467481 = 31467554
373 + 31467181 = 31467554
397 + 31467157 = 31467554
421 + 31467133 = 31467554
487 + 31467067 = 31467554
577 + 31466977 = 31467554
661 + 31466893 = 31467554

Showing the first eight; more decompositions exist.
