Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499852, here are decompositions:

19 + 31499833 = 31499852
193 + 31499659 = 31499852
421 + 31499431 = 31499852
523 + 31499329 = 31499852
541 + 31499311 = 31499852
613 + 31499239 = 31499852
691 + 31499161 = 31499852
829 + 31499023 = 31499852

Showing the first eight; more decompositions exist.
