Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31464524, here are decompositions:

31 + 31464493 = 31464524
43 + 31464481 = 31464524
61 + 31464463 = 31464524
73 + 31464451 = 31464524
97 + 31464427 = 31464524
103 + 31464421 = 31464524
127 + 31464397 = 31464524
331 + 31464193 = 31464524

Showing the first eight; more decompositions exist.
