Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483192, here are decompositions:

23 + 31483169 = 31483192
29 + 31483163 = 31483192
131 + 31483061 = 31483192
353 + 31482839 = 31483192
359 + 31482833 = 31483192
431 + 31482761 = 31483192
449 + 31482743 = 31483192
509 + 31482683 = 31483192

Showing the first eight; more decompositions exist.
