Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588076, here are decompositions:

73 + 31588003 = 31588076
97 + 31587979 = 31588076
127 + 31587949 = 31588076
199 + 31587877 = 31588076
277 + 31587799 = 31588076
283 + 31587793 = 31588076
379 + 31587697 = 31588076
643 + 31587433 = 31588076

Showing the first eight; more decompositions exist.
