Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31507622, here are decompositions:

31 + 31507591 = 31507622
61 + 31507561 = 31507622
163 + 31507459 = 31507622
271 + 31507351 = 31507622
379 + 31507243 = 31507622
463 + 31507159 = 31507622
541 + 31507081 = 31507622
613 + 31507009 = 31507622

Showing the first eight; more decompositions exist.
