Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588046, here are decompositions:

43 + 31588003 = 31588046
67 + 31587979 = 31588046
97 + 31587949 = 31588046
103 + 31587943 = 31588046
229 + 31587817 = 31588046
349 + 31587697 = 31588046
613 + 31587433 = 31588046
619 + 31587427 = 31588046

Showing the first eight; more decompositions exist.
