Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461574, here are decompositions:

3 + 31461571 = 31461574
5 + 31461569 = 31461574
17 + 31461557 = 31461574
41 + 31461533 = 31461574
233 + 31461341 = 31461574
281 + 31461293 = 31461574
293 + 31461281 = 31461574
383 + 31461191 = 31461574

Showing the first eight; more decompositions exist.
