Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31462994, here are decompositions:

61 + 31462933 = 31462994
97 + 31462897 = 31462994
163 + 31462831 = 31462994
223 + 31462771 = 31462994
271 + 31462723 = 31462994
421 + 31462573 = 31462994
463 + 31462531 = 31462994
487 + 31462507 = 31462994

Showing the first eight; more decompositions exist.
