Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567406, here are decompositions:

37 + 31567369 = 31567406
109 + 31567297 = 31567406
127 + 31567279 = 31567406
139 + 31567267 = 31567406
193 + 31567213 = 31567406
433 + 31566973 = 31567406
439 + 31566967 = 31567406
487 + 31566919 = 31567406

Showing the first eight; more decompositions exist.
