Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31535864, here are decompositions:

37 + 31535827 = 31535864
43 + 31535821 = 31535864
67 + 31535797 = 31535864
193 + 31535671 = 31535864
271 + 31535593 = 31535864
313 + 31535551 = 31535864
397 + 31535467 = 31535864
487 + 31535377 = 31535864

Showing the first eight; more decompositions exist.
