Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31461098, here are decompositions:

61 + 31461037 = 31461098
127 + 31460971 = 31461098
181 + 31460917 = 31461098
307 + 31460791 = 31461098
397 + 31460701 = 31461098
421 + 31460677 = 31461098
547 + 31460551 = 31461098
601 + 31460497 = 31461098

Showing the first eight; more decompositions exist.
