Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462898, here are decompositions:

67 + 31462831 = 31462898
127 + 31462771 = 31462898
139 + 31462759 = 31462898
151 + 31462747 = 31462898
307 + 31462591 = 31462898
367 + 31462531 = 31462898
457 + 31462441 = 31462898
541 + 31462357 = 31462898

Showing the first eight; more decompositions exist.
