Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547996, here are decompositions:

3 + 31547993 = 31547996
37 + 31547959 = 31547996
43 + 31547953 = 31547996
79 + 31547917 = 31547996
157 + 31547839 = 31547996
163 + 31547833 = 31547996
313 + 31547683 = 31547996
367 + 31547629 = 31547996

Showing the first eight; more decompositions exist.
