Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591134, here are decompositions:

41 + 31591093 = 31591134
67 + 31591067 = 31591134
73 + 31591061 = 31591134
97 + 31591037 = 31591134
103 + 31591031 = 31591134
191 + 31590943 = 31591134
193 + 31590941 = 31591134
227 + 31590907 = 31591134

Showing the first eight; more decompositions exist.
