Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31583204, here are decompositions:

67 + 31583137 = 31583204
73 + 31583131 = 31583204
157 + 31583047 = 31583204
181 + 31583023 = 31583204
223 + 31582981 = 31583204
307 + 31582897 = 31583204
313 + 31582891 = 31583204
571 + 31582633 = 31583204

Showing the first eight; more decompositions exist.
