Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496254, here are decompositions:

113 + 31496141 = 31496254
131 + 31496123 = 31496254
197 + 31496057 = 31496254
227 + 31496027 = 31496254
521 + 31495733 = 31496254
563 + 31495691 = 31496254
593 + 31495661 = 31496254
653 + 31495601 = 31496254

Showing the first eight; more decompositions exist.
