Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31520564, here are decompositions:

37 + 31520527 = 31520564
67 + 31520497 = 31520564
73 + 31520491 = 31520564
157 + 31520407 = 31520564
193 + 31520371 = 31520564
211 + 31520353 = 31520564
331 + 31520233 = 31520564
547 + 31520017 = 31520564

Showing the first eight; more decompositions exist.
