Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567542, here are decompositions:

29 + 31567513 = 31567542
31 + 31567511 = 31567542
113 + 31567429 = 31567542
131 + 31567411 = 31567542
173 + 31567369 = 31567542
229 + 31567313 = 31567542
263 + 31567279 = 31567542
271 + 31567271 = 31567542

Showing the first eight; more decompositions exist.
