Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588034, here are decompositions:

31 + 31588003 = 31588034
73 + 31587961 = 31588034
157 + 31587877 = 31588034
241 + 31587793 = 31588034
337 + 31587697 = 31588034
601 + 31587433 = 31588034
607 + 31587427 = 31588034
613 + 31587421 = 31588034

Showing the first eight; more decompositions exist.
