Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588532, here are decompositions:

61 + 31588471 = 31588532
163 + 31588369 = 31588532
181 + 31588351 = 31588532
211 + 31588321 = 31588532
229 + 31588303 = 31588532
331 + 31588201 = 31588532
571 + 31587961 = 31588532
673 + 31587859 = 31588532

Showing the first eight; more decompositions exist.
