Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528232, here are decompositions:

3 + 31528229 = 31528232
19 + 31528213 = 31528232
61 + 31528171 = 31528232
139 + 31528093 = 31528232
163 + 31528069 = 31528232
523 + 31527709 = 31528232
691 + 31527541 = 31528232
709 + 31527523 = 31528232

Showing the first eight; more decompositions exist.
