Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532752, here are decompositions:

3 + 31532749 = 31532752
59 + 31532693 = 31532752
113 + 31532639 = 31532752
179 + 31532573 = 31532752
263 + 31532489 = 31532752
491 + 31532261 = 31532752
821 + 31531931 = 31532752
1103 + 31531649 = 31532752

Showing the first eight; more decompositions exist.
