Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495562, here are decompositions:

61 + 31495501 = 31495562
139 + 31495423 = 31495562
211 + 31495351 = 31495562
229 + 31495333 = 31495562
349 + 31495213 = 31495562
409 + 31495153 = 31495562
499 + 31495063 = 31495562
613 + 31494949 = 31495562

Showing the first eight; more decompositions exist.
