Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31574622, here are decompositions:

59 + 31574563 = 31574622
173 + 31574449 = 31574622
179 + 31574443 = 31574622
193 + 31574429 = 31574622
293 + 31574329 = 31574622
389 + 31574233 = 31574622
419 + 31574203 = 31574622
421 + 31574201 = 31574622

Showing the first eight; more decompositions exist.
