Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495502, here are decompositions:

79 + 31495423 = 31495502
151 + 31495351 = 31495502
229 + 31495273 = 31495502
331 + 31495171 = 31495502
349 + 31495153 = 31495502
439 + 31495063 = 31495502
499 + 31495003 = 31495502
523 + 31494979 = 31495502

Showing the first eight; more decompositions exist.
