Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492462, here are decompositions:

41 + 31492421 = 31492462
59 + 31492403 = 31492462
383 + 31492079 = 31492462
389 + 31492073 = 31492462
401 + 31492061 = 31492462
431 + 31492031 = 31492462
479 + 31491983 = 31492462
503 + 31491959 = 31492462

Showing the first eight; more decompositions exist.
