Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495922, here are decompositions:

43 + 31495879 = 31495922
103 + 31495819 = 31495922
181 + 31495741 = 31495922
193 + 31495729 = 31495922
229 + 31495693 = 31495922
331 + 31495591 = 31495922
421 + 31495501 = 31495922
499 + 31495423 = 31495922

Showing the first eight; more decompositions exist.
