Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31586150, here are decompositions:

3 + 31586147 = 31586150
19 + 31586131 = 31586150
73 + 31586077 = 31586150
97 + 31586053 = 31586150
313 + 31585837 = 31586150
367 + 31585783 = 31586150
373 + 31585777 = 31586150
487 + 31585663 = 31586150

Showing the first eight; more decompositions exist.
