Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450546, here are decompositions:

3 + 31450543 = 31450546
5 + 31450541 = 31450546
59 + 31450487 = 31450546
137 + 31450409 = 31450546
233 + 31450313 = 31450546
383 + 31450163 = 31450546
443 + 31450103 = 31450546
503 + 31450043 = 31450546

Showing the first eight; more decompositions exist.
