Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31452704, here are decompositions:

37 + 31452667 = 31452704
97 + 31452607 = 31452704
211 + 31452493 = 31452704
223 + 31452481 = 31452704
337 + 31452367 = 31452704
421 + 31452283 = 31452704
463 + 31452241 = 31452704
523 + 31452181 = 31452704

Showing the first eight; more decompositions exist.
