Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31455622, here are decompositions:

89 + 31455533 = 31455622
101 + 31455521 = 31455622
173 + 31455449 = 31455622
251 + 31455371 = 31455622
353 + 31455269 = 31455622
383 + 31455239 = 31455622
461 + 31455161 = 31455622
491 + 31455131 = 31455622

Showing the first eight; more decompositions exist.
