Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31448802, here are decompositions:

61 + 31448741 = 31448802
83 + 31448719 = 31448802
89 + 31448713 = 31448802
103 + 31448699 = 31448802
109 + 31448693 = 31448802
163 + 31448639 = 31448802
181 + 31448621 = 31448802
199 + 31448603 = 31448802

Showing the first eight; more decompositions exist.
