Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527830, here are decompositions:

3 + 31527827 = 31527830
13 + 31527817 = 31527830
43 + 31527787 = 31527830
127 + 31527703 = 31527830
307 + 31527523 = 31527830
331 + 31527499 = 31527830
349 + 31527481 = 31527830
487 + 31527343 = 31527830

Showing the first eight; more decompositions exist.
