Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31562432, here are decompositions:

3 + 31562429 = 31562432
43 + 31562389 = 31562432
103 + 31562329 = 31562432
151 + 31562281 = 31562432
313 + 31562119 = 31562432
379 + 31562053 = 31562432
409 + 31562023 = 31562432
439 + 31561993 = 31562432

Showing the first eight; more decompositions exist.
