Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615964, here are decompositions:

13 + 31615951 = 31615964
43 + 31615921 = 31615964
73 + 31615891 = 31615964
157 + 31615807 = 31615964
181 + 31615783 = 31615964
223 + 31615741 = 31615964
313 + 31615651 = 31615964
421 + 31615543 = 31615964

Showing the first eight; more decompositions exist.
