Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523962, here are decompositions:

23 + 31523939 = 31523962
293 + 31523669 = 31523962
311 + 31523651 = 31523962
383 + 31523579 = 31523962
521 + 31523441 = 31523962
563 + 31523399 = 31523962
653 + 31523309 = 31523962
683 + 31523279 = 31523962

Showing the first eight; more decompositions exist.
