Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452644, here are decompositions:

37 + 31452607 = 31452644
61 + 31452583 = 31452644
73 + 31452571 = 31452644
127 + 31452517 = 31452644
151 + 31452493 = 31452644
163 + 31452481 = 31452644
193 + 31452451 = 31452644
277 + 31452367 = 31452644

Showing the first eight; more decompositions exist.
