Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31552748, here are decompositions:

67 + 31552681 = 31552748
109 + 31552639 = 31552748
127 + 31552621 = 31552748
211 + 31552537 = 31552748
397 + 31552351 = 31552748
439 + 31552309 = 31552748
541 + 31552207 = 31552748
691 + 31552057 = 31552748

Showing the first eight; more decompositions exist.
