Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489546, here are decompositions:

5 + 31489541 = 31489546
83 + 31489463 = 31489546
113 + 31489433 = 31489546
197 + 31489349 = 31489546
317 + 31489229 = 31489546
353 + 31489193 = 31489546
449 + 31489097 = 31489546
467 + 31489079 = 31489546

Showing the first eight; more decompositions exist.
