Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462178, here are decompositions:

37 + 31462141 = 31462178
109 + 31462069 = 31462178
157 + 31462021 = 31462178
199 + 31461979 = 31462178
229 + 31461949 = 31462178
337 + 31461841 = 31462178
367 + 31461811 = 31462178
607 + 31461571 = 31462178

Showing the first eight; more decompositions exist.
