Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452554, here are decompositions:

37 + 31452517 = 31452554
61 + 31452493 = 31452554
73 + 31452481 = 31452554
103 + 31452451 = 31452554
271 + 31452283 = 31452554
313 + 31452241 = 31452554
373 + 31452181 = 31452554
433 + 31452121 = 31452554

Showing the first eight; more decompositions exist.
