Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464442, here are decompositions:

3 + 31464439 = 31464442
41 + 31464401 = 31464442
83 + 31464359 = 31464442
101 + 31464341 = 31464442
173 + 31464269 = 31464442
293 + 31464149 = 31464442
479 + 31463963 = 31464442
521 + 31463921 = 31464442

Showing the first eight; more decompositions exist.
