Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495832, here are decompositions:

13 + 31495819 = 31495832
31 + 31495801 = 31495832
79 + 31495753 = 31495832
103 + 31495729 = 31495832
139 + 31495693 = 31495832
229 + 31495603 = 31495832
241 + 31495591 = 31495832
331 + 31495501 = 31495832

Showing the first eight; more decompositions exist.
