Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31495658, here are decompositions:

67 + 31495591 = 31495658
157 + 31495501 = 31495658
211 + 31495447 = 31495658
241 + 31495417 = 31495658
307 + 31495351 = 31495658
487 + 31495171 = 31495658
541 + 31495117 = 31495658
709 + 31494949 = 31495658

Showing the first eight; more decompositions exist.
