Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532388, here are decompositions:

47 + 31532341 = 31532388
59 + 31532329 = 31532388
109 + 31532279 = 31532388
127 + 31532261 = 31532388
179 + 31532209 = 31532388
271 + 31532117 = 31532388
317 + 31532071 = 31532388
367 + 31532021 = 31532388

Showing the first eight; more decompositions exist.
