Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522054, here are decompositions:

41 + 31522013 = 31522054
101 + 31521953 = 31522054
167 + 31521887 = 31522054
191 + 31521863 = 31522054
383 + 31521671 = 31522054
461 + 31521593 = 31522054
587 + 31521467 = 31522054
677 + 31521377 = 31522054

Showing the first eight; more decompositions exist.
