Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450452, here are decompositions:

23 + 31450429 = 31450452
29 + 31450423 = 31450452
31 + 31450421 = 31450452
41 + 31450411 = 31450452
43 + 31450409 = 31450452
83 + 31450369 = 31450452
101 + 31450351 = 31450452
139 + 31450313 = 31450452

Showing the first eight; more decompositions exist.
