Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461622, here are decompositions:

53 + 31461569 = 31461622
89 + 31461533 = 31461622
281 + 31461341 = 31461622
431 + 31461191 = 31461622
443 + 31461179 = 31461622
449 + 31461173 = 31461622
461 + 31461161 = 31461622
509 + 31461113 = 31461622

Showing the first eight; more decompositions exist.
