Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522174, here are decompositions:

71 + 31522103 = 31522174
83 + 31522091 = 31522174
113 + 31522061 = 31522174
197 + 31521977 = 31522174
311 + 31521863 = 31522174
461 + 31521713 = 31522174
491 + 31521683 = 31522174
503 + 31521671 = 31522174

Showing the first eight; more decompositions exist.
