Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492036, here are decompositions:

3 + 31492033 = 31492036
5 + 31492031 = 31492036
47 + 31491989 = 31492036
53 + 31491983 = 31492036
449 + 31491587 = 31492036
479 + 31491557 = 31492036
509 + 31491527 = 31492036
683 + 31491353 = 31492036

Showing the first eight; more decompositions exist.
