Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589850, here are decompositions:

7 + 31589843 = 31589850
23 + 31589827 = 31589850
31 + 31589819 = 31589850
73 + 31589777 = 31589850
79 + 31589771 = 31589850
113 + 31589737 = 31589850
139 + 31589711 = 31589850
157 + 31589693 = 31589850

Showing the first eight; more decompositions exist.
