Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31486202, here are decompositions:

73 + 31486129 = 31486202
79 + 31486123 = 31486202
193 + 31486009 = 31486202
229 + 31485973 = 31486202
271 + 31485931 = 31486202
313 + 31485889 = 31486202
331 + 31485871 = 31486202
379 + 31485823 = 31486202

Showing the first eight; more decompositions exist.
