Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31588044, here are decompositions:

41 + 31588003 = 31588044
83 + 31587961 = 31588044
101 + 31587943 = 31588044
151 + 31587893 = 31588044
167 + 31587877 = 31588044
227 + 31587817 = 31588044
251 + 31587793 = 31588044
263 + 31587781 = 31588044

Showing the first eight; more decompositions exist.
