Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567602, here are decompositions:

43 + 31567559 = 31567602
89 + 31567513 = 31567602
151 + 31567451 = 31567602
173 + 31567429 = 31567602
191 + 31567411 = 31567602
233 + 31567369 = 31567602
331 + 31567271 = 31567602
383 + 31567219 = 31567602

Showing the first eight; more decompositions exist.
