Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31496194, here are decompositions:

53 + 31496141 = 31496194
71 + 31496123 = 31496194
137 + 31496057 = 31496194
167 + 31496027 = 31496194
347 + 31495847 = 31496194
461 + 31495733 = 31496194
503 + 31495691 = 31496194
593 + 31495601 = 31496194

Showing the first eight; more decompositions exist.
