Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31450544, here are decompositions:

3 + 31450541 = 31450544
61 + 31450483 = 31450544
157 + 31450387 = 31450544
193 + 31450351 = 31450544
337 + 31450207 = 31450544
487 + 31450057 = 31450544
523 + 31450021 = 31450544
577 + 31449967 = 31450544

Showing the first eight; more decompositions exist.
