Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522322, here are decompositions:

79 + 31522243 = 31522322
103 + 31522219 = 31522322
193 + 31522129 = 31522322
331 + 31521991 = 31522322
439 + 31521883 = 31522322
673 + 31521649 = 31522322
751 + 31521571 = 31522322
823 + 31521499 = 31522322

Showing the first eight; more decompositions exist.
