Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462088, here are decompositions:

19 + 31462069 = 31462088
67 + 31462021 = 31462088
109 + 31461979 = 31462088
127 + 31461961 = 31462088
139 + 31461949 = 31462088
271 + 31461817 = 31462088
277 + 31461811 = 31462088
571 + 31461517 = 31462088

Showing the first eight; more decompositions exist.
